1.Well in my case I find it wrong When u take two male characters who do NOT have love between each other and draw graphic fan art of them.
2.(If u 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 u think they LOVE each other but they don't at the most it's brotherly if even that.
3.When u take brothers of any relatives of all people and put them together it tends to make the haters hate more.What's with and incest?!
