People who think that all anime is "naughty tentacles", all male characters are "humping like bunnies to please the weirdo fangirls" and all visual novels are "hentai".
There's a special place in hell for those people. And you know what... it might actually be justified in some way. By western standards, the Japanese are a very odd people (their pull-your-weight work-standard, obsession with making everything cute to make a thin barrier to protect themselves with their crippling despair, and the fact that Cat Soup exists) and some people just take a few darkly comic jokes in anime too far without knowing anything about the anime itself.
"naughty tentacles" aren't actually all that tolerated in Japan, for obvious reasons, and it gives them a somewhat bad image.
I also fucking hate popular LPers. They are all obnoxious pricks who made me laugh once or twice, but only out of despair and as a defense mechanism. I fucking hate those people. One LPer/steamer who is actually funny, Supergreatfriend, is known for his bonderline stoicism, choice of games that are so bad it's good, and blatant disregard for offensive or misogynistic things, before going into emotional rants about something minor and trivial. And he's entertaining, funny, but gets very few views.
Pewdiepie is a loud, idiotic, obnoxious douchebag whose only slightly entertaining trait is his absurd hatred of wooden containment mechanisms. And even then, that's about as entertaining as giving a 3-hour lecture on the history of etcha-sketches.
