Well I hate to say that I actually agree that the "hairy" Billy is pret-ty unattractive in my opinion as well. Though some of the other Billy fanarts are ok because the fanartist drew him less hairy and smooth looking which are fantastic! But this......meh...not so good. I'm so used to pretty bishonens and how pretty the original Billy looks. [link] Of course it is without a doubt frustrating to see how other people giving out their opinions the wrong and immature way. Like......"Yuri is ok because it's girl on girl, but I don't understand the point of yaoi." No matter what people's opinions are, they are entitled to have their own opinions. To each their own way. We do have a lot of people showing their expressions the weird, stubborn and retarded way in this entire planet. But that's them and nothing much we can do about it.
And as for the trolls spamming part, it's best to not give them ANY attention at all because that's all what they want from you, and fall into their trap. Just ignore them and move on. Getting them back won't do much good trust me, it's not worth it.
