Sturgeon's law. I don't know what it is about this, but it just rubs me the wrong way. I guess I just don't like the generalization of "90% of everything is crap". It seems like such a cynical, depressing mindset.
Also, I'm just against the whole idea of "This percentage of ______ is good / bad." like it's a sure fact and is used as an end-all to any debate or discussion.
Other than that...
- People who still debate whether anime are cartoons or not.
Yes. Yes they fucking are. I still can not in the right mind believe that this is still an argument going on. I firmly believe that people who say anime are not cartoons do not know what cartoons are.
- Long anime / manga / light novel titles.
Long titles that translate to stuff like "My Little Sister Can't Be This Cute!", or (and this is an anime I like) "No Matter How I Look At It, It's You Guys' Fault I'm Unpopular!" That's not a title, that's a phrase. An entire sentence even. All that's saying to me is "Look at me, I've made a unconventional title for my book / anime, aren't I so funny?" (That should seriously be the title for one of these things, because then I'd know they're full of shit.)
-The term "Waifu"
No matter how it's used, even if it's ironically, it just irritates me.
