I have seen the "You don't like it because it's you" excuse for literally every modern Wojak variation so far, which says less about the "you" and more about the actual motivation behind them and why they are inferior to past variations. With that in mind, even Rage Face guy here has more of a right to exist today, really.

Pretty much my thoughts on the Coomer "meme".
As much as I dislike all other Pepe and Wojak variations at least there was something behind them and followed by an argument to a certain degree,despite being used to whoever the poster dislike.
The Coomer like the other variations is an extreme depiction of a specific group of people and just doesn't have any right to exist because:
-there are people who masturbate almost every day and still live an healthy life so as a premise it just falls apart,especially when this is so overly-specific
-It's just a replacement for "Cumbrain",which was so overused that it got filtered in less than a day.
-Unlike the others is just a way to annoy someone,in the most juvenile and childish way.like a teen would do.
Which is what a lot of 4chan anons are nowadays.

About the Discord and Reddit part,a lot of 4chan users also happen to use those sites as well like many YT commenters.So far is the lowest point for Wojaks variations,all around a forced meme.

So there isn't that much difference
