Nobody gets mad at someone just for having shit taste. It's only when someone with shit taste tries to says that X is better than Y.
If you like Naruto, Bleach, One Piece, or cute girls doing cute things, etc., that's fine, just don't call it the greatest anime ever around people that know better and expect them to pat you on the back.
I like fast food, but I don't walk into a 4 star restaurant, order a Big Mac and then complain when they don't serve Big Macs and tell them how Big Mac are the greatest food in existence and that there's nothing inherently wrong with liking McDonalds .
tl;dr people with Asperger's are annoying.
