I see where your coming from about this, but I have a few things to say.
First, I know the fact that I complain about some fetish art, but its subject is very unappealing to not just me, but many others on this site.
Second, I will criticize the things I find if they need it. And no, I'm not talking about what the picture is about, I'm talking about the actual quality.
Third, I've actually gave my opinions and criticism about the quality of art to more than just fetish artists. To be fair, if there is a well drawn fetish art that I don't like, I'll either say nothing about the quality or mention it briefly to show that I don't dislike the style, just the subject of the art.
