I have asked a few times why PDP deserves all the hate. The best answer I got is "look it up yourself". I did, and the only things I found were many years old, and in each instance (of which there aren't that many) he apologized publicly and acknowledged that things got out of hand. To me, his apologies seem sincere and genuine - none of that "I'm sorry I got caught" bullshit that actual scumbags are known for.
I don't watch PewDiePie but he's alright best I can tell. If I've missed something, please let me know what that is, and be specific because I genuinely can't find it.
