Well, I go exercise for the first time in a while and when I return everything is on fire. Lesson learned: I'll just avoid exercising for...uh...the good of everyone. Yeah, that's it.
Now, on the more serious bit of this:
First of all, Im going to be plain honest here, this whole drama is completely ridiculous. It doesn't matter who is or who isn't a champion. It's just a game. It has no real effects on real life.
I have no idea of how this thing happened, but based on what my intel tells me, it's all because the Black protagonist, whatever his name is (I feel that the 5 seconds required to Google him are not worth it.) was not drawn as part of a collab thing because he wasn't considered a champion by normal standards or something like that. I just gotta tell you Trollkitten, as a third-rate artist myself, I've drawn stuff, lots of it. But the things I don't draw are things people force me to draw. It's not okay to make a big protest trying to make the artists go, feel bad and draw him anyway. It doesn't work that way
Then it seems you tried to apologize for it and then the mods deleted the topic which made you angry. I find understandable that you are angry, but consider how the TPP mods feel about all the drama and the after drama. They just want to bury the issue because it is killing the TPP subreddit. I feel as if at this rate you could single-handedly kill that subreddit with drama outbursts alone. Posting your anger in different boards isn't going to solve anything at all under no conditions. It'll just make matter a worse and not seem like you're trying to apologize, specially if you go and use gigantic letters to make your points. Everyone in reddit can read, Trollkitten. Making it bigger will just make it annoying on the eyes.
In the end I feel like this is a very unfortunate situation that in the end of the day it's completely meaningless. I feel like I'd believe that even if I still liked TPP at least one bit. If you'd like, I'd suggest you to game a bit with those you consider your friends and want nearby. It's really soothing and helpful, because continuing to try at those subreddits right now will be futile.
