1.Well in my case I find it wrong When you take two male characters who do NOT have love between each other and draw graphic fan art of them.
2.(If you want yaoi read/watch Shonen ai.Those are full of yaoi)If it's Shonen that means there is NO chance of yaoi,People take two guys and put them together.Example:Naruto and Sasuke I know you think they LOVE each other but they don't at the most it's brotherly if even that.
3.When you take brothers or any relatives of all people and put them together it tends to make the haters hate more.What's with and incest?!
