I have my fair share of het ships, but most of my OTPs happen to be BL. I just think that a lot of het pairs are portrayed really dull and because it's het, apparently that makes it okay.
It mostly just aggravates me when the female character is emotionally weakened, to the point that I can't imagine it anymore. I'm thinking about Nami from One Piece and Sakura from Naruto. I mean, yeah, they're girls, and Sakura cries and she is very emotional based, but I can't see her submitting to any one so easily. Like Hikari from Pokemon. If anyone tried to make a move on her she would do something about it.
Reasons I can't find any good SaiSaku because Sai is usually portrayed all creepy-like. Along with how I realized that not everyone will have the same opinion as I and SasuSaku will be there and dlskfjdlfkjeslk nope nope nope.
