Alright, listen here, kiddos, let ol' Uncle Fridge tell you about the time he was a brony.
It was the summer of 2011, and I was bored as all darn heck and looking for something to do. One day I moseyed into the IRC channel and chatted up a couple of these brony fellers and hey, they seemed like real nice folk! Now, I was always pretty nervous about trying new things, especially a cartoon show made for little girls, but I was looking to kill some time and decided hey, why don't I try this show out?
So I watched the first season, and I thought to myself, "okay, this is a decent show, I really like the art style." And that, ladies and gentlemen, was the hook that caught this ol' snapper: the art, namely, the _fan_art. There was soooooo much. And it was all. So. Fuckin. Quality. I was absolutely enthralled, so enthralled, in fact, that I went through the entire image gallery on the MLP entry in a single August night. (This was back when it was under 1,000 images, I think.)
So I became a brony. Soon I also found out that my best friend at the time was also a brony. What are the odds? (High, we were a couple of introverted nerds on the internet in 2011, it was impossible to be unaffected). I stuck around for the next year or so, enjoying myself, watching the show, socializing, looking at all the arts, reading Equestria Daily, and so on. I wasn't telling people I was a brony because I was already "that guy" at school and I didn't feel like committing social suicide, but it was a fun thing on the side. Then things started to change.
I think it was around when Derpy Hooves' voice was changed in reruns of that one Applejack episode when the tone of discourse among bronies began to shift. The fandom had finally achieved an enormous level of recognition from the show's creators and had it yanked away in the name of political correctness. The positivity that drew me in initially gave way to vitriol and backlash and suddenly friendship wasn't magic anymore. After this it seemed like pornographic materials became much more prevalent. I'm sure you all know how far it goes. Basically, when you start to see a community devolve into discussions of "crotchboobs," "bronycon orgy," and this thing-
-you start to wonder what you're doing here.
To be honest, all this isn't even what made me leave. It was Twilacorn. I didn't like the direction the show was going in, I didn't like the direction the fandom was going in, and I felt like Season 3 was trying to wrap things up. There was also an art drought that summer, and I think I was getting into Homestuck at the same time, and when I saw the Equestria Girls thing I think I was finally sufficiently embarrassed with myself for liking this thing. The phase ended.
I didn't read through the thread so I don't know if he responded, but I feel like OP is intimidated by the show because he doesn't understand why something inherently female is being consumed by so many males. Basically, I don't think OP's problem is with MLP, I think it's with the people involved with it. Let me say that the bronies are not typified by the unsavory characters that make up their public persona. It's just that there seem to be an absolute glut of unsavory characters.
Think of it this way: this show was not made for you. This show was designed as a reestablishment of a brand designed to sell little girls toy ponies. L. Faust came along and decided to give it a feminist bend along the way, and I'm very glad she did that. Women and girls need to see that there is no right way to be female. They need to have their own media that exists outside of patriarchal hands, that they can call their own, that they can point to and say "We have this, this is ours, and you can't take this from us."
FiM was supposed to be this, to a minor degree. No one expected it to appeal to males in the way that it did. At a point, however, bronies ceased to be a periphery demographic and attempted to make the entire franchise cater to their desires. That is what I find most abhorrent about this whole deal. It does not challenge manliness, as so many writers over the last four years have asserted. Instead, it challenges women. Truly, bronies are still very masculine because they continue to do the one thing men have always done: attempt to subject femininity to their will.
Or maybe the OP's just sick of pony spam, I don't know.
TL;DR – bronies r dum, Women's Studies 101 gesticulation, rip me to shreds like one of your French ponies, I just spent an hour writing this and it's 3 AM so I don't give a fuck about your responses.
Now ol' Uncle Fridgey's going to bed. Nighty Night.
