i don't have a problem with yuri or yaoi anime, and i don't have anything against homosexuals either. in fact, i enjoyed the anime 'gravitation' - a yaoi anime. nothing hardcore, but yaoi none the less.
those who say they despise homosexuals... i'd say, they're just afraid of what others will think of them if they say that don't mind them. there are a lot of people who are afraid that people will think they like homosexuals if they say they're ok with it - which i think is pretty understandable, but foolish never the less. it's downright immature. and if you think about it, it's sexist too. so before someone decides to tell people that they dislike homosexuals, think about what you're actually saying.
