@X-Singular and BSoD
Oh goodie, a birthday shitstorm!

Anyway, my argument:
I can see two sides to this argument, and like X-Singular said, its not cloppers vs. non-cloppers, its what’s acceptable and not acceptable.
First, let’s observe the clopping community and Pony r34, or actually, just the 34th Rule of the Internet:
“Rule 34: There is porn of it; no exceptions”
To be honest, this is both a joke and harsh truth. The wording suggests that any object at any time can be fapped to by someone in the world.
At the same time, it describes the extent of pornography across the internet, including the steady rise in fandom-related pornography. Characters from all across the genres and movie serials are now being drawn by artists in sexual or sensual positions.
Now, is Poni the only fandom to suffer from this?
Absolutely Not!
Porn exists across nearly every, if not ALL, fandoms that exist. In one way or another, it exists. Name a series. Star Wars, Lord of the Rings, Spongebob, Super Mario, the Simpsons, Family Guy, Avatar: the Last Airbender, Legend of Korra, Gravity Falls, Adventure Time, Fairly Odd Parents, Powerpuff Girls, Foster’s Home for Imaginary Friends, Marvel Universe, Sonic, Mass Effect, Team Fortress, Left4Dead, etc.
You’re going to find some porn in ALL of those fandoms
But is Poni the fandom that is most controversial for this?
Possibly
The reason being this: My Little Pony: Friendship is Magic IS a show intended at a younger audience, which happens to be feminine in majority.
The fact is BRONIES are a fandom based upon this show, which was created so that older audiences can tolerate it too (which the bronies actually developed a love for the show because of that). We are estimated 14 – 23 year olds who are both male and female who happen to watch the show too.
But here’s where the problems start: little girls don’t know about sex or porn, and do not have drawing or writing skills. So are they making the porn?
Nope.
Members of the Brony Fandom do.
The teenage to adult MALES (and females) of the Brony Community make the porn, because they are old enough have the necessary skills, and the mindsets, to do it.
That’s why we are a controversy
It’s because we stick out like a sore thumb in the viewers of the show, and Hasbro and Studio B, though markets MLP, hasn’t done so much as basic advertisements for the show, relying on profits to be made from the toy line that the series advertises.
But that’s for the little girls. For other viewers…they actually have to rely on the brony fandom to spread the word.
When we talk about the show, we do get some people interested, and when we get people interested, they watch the show, and from there, they make the decision, and inevitably, we get people to watch the show, which in turn, makes Hasbro profits.
But methods of communication?
Well, we have what most bronies do: calmly and reasonably talk about the show, be assertive, and explain as best as we can about the show, done through forums, chat rooms, and such.
But, inner-fandom communication relies on the fandom’s members. To keep ourselves strong, we keep together. We communicate using various sites, using words, images, flash games, and videos…
Remember the fandom’s age group? Teenage to Young Adult Males? And that they happen to be internet users?
What’s associated with that group, generally?
Sexuality
Yes. SEXUALITY
Guess what? Much of the bronies are made up of teenage to young adult internet-frequent MALES, who are associated with sexuality.
And guess what? That transfers into the fandom.
That’s why we get R34
That’s why it exists
But what does this have to do with KYM’s image gallery specifically, you ask?
Well, just about everything
You see, our rules say no porn or gore, which means, well…no porn or gore
but you have to classify “porn”
“porn” is explicit sexual content, like actual sexual intercourse, or ones glans or sex being shown explicitly in a sexual way.
“sexualization” is a step down from that. The character in question is positioned and dressed in a sexual or seductive way, or sometimes in a suggested sexual act, but not explicitly, so you can’t say its really porn.

Luna is depicted in a seductive and sexual manner in this picture, obvious by her facial expression and her attire
Sexualizations are what can be called ‘fap fuel’, but its not ‘porn’.
But is it okay for KYM?
That’s a matter of opinion.
But here’s X-Singular’s point: R34 and Sexualizations are on Google, including results from KYM. Its a controversy how much R34 and Sexualizations exist for a fandom based around a younger feminine show, and how easily it can be found by just pressing a few keys and a few mouse clicks. The most controversial part: its not something you have to dig for and find
GOOGLE & OTHER BASIC SEARCH ENGINES
SHOW
PONY R34
RESULTS
So any little girl wanting to look up her favorite pony could end up seeing that character in a way that is not appropriate for that age.
As for KYM too, there’s a substantial amount of bronies who either don’t all together or have limited tolerance or preference to sexualizations. Like me. I don’t mind it mostly, but it gets really annoying for it to come up constantly. And I see some users not liking it all together. Plus, it kind of defames us, especially with non-brony users, seeing the most favorited or most like tab containing pony sexualizations without the “less ponies” tab on.
Personal preference on Pony R34 or sexualizations in general?
Personally, I don’t mind it. Its a fandom thing, but I don’t go out on a whim to look at sexualizations, and not at all for R34. But sometimes, I do indulge myself a bit with a Chrysalis pic..
Plus, if you read Mine and Joe Amethyst’s story, “Red Light City”, you know we’re not setting it up for a child-friendly environment (for those who don’t know, there’s sex, drugs, murder, and alcohol involved).
But at least our work is kept in wraps on a site that you have to specifically look for, and fortunately, FIMFiction is not something little girls look for.
I’ve also become a bit more lenient on what I say I can tolerate and sometimes like.
Such as this:

I remember Tim the Enchanter if I recall showing this to me for the first time a while ago. I was initially phased out, but I can honestly say now its not that bad
Back to KYM and the whole controversy though, we should monitor what goes on and what doesn’t, to make sure we’re not passing any lines. We should also keep a watch on the content of what images make it on.
An example is Molestia. Molestia has her own page, yet we always upload JJ’s comics to the main entry, and we all know that Molestia can get pretty explicit at times. So, that’s one thing we can purge, and instead, transfer it over to Molestia’s gallery.
As for sexualizations in general, we should establish what’s acceptable and not acceptable, and be more vigilant in letting uploaders know that. Establish a firm line, and ensure its not crossed in any way. If it does cross that line, take it down. This way, we can clean up a bit on the gallery, and reduce the amount of explicit material in it.
tl;dr – Pony Porn exists. We need to deal with it, but we can clean up KYM a bit better, and sort what stays and what doesn’t, and what needs to go where in our galleries.
