I did as you suggested and I saw people singing slurs around like it's nothing almost immediately. I suppose perhaps given that you have used one in your comment I shouldn't be surprised that it passes you by, but that is exactly the kind of overt racism/sexism/homophobia/transphobia that, I assume, the previous comment was talking about.

Edit: oh, and the rest of it is mostly loli porn. So. That's a good reason to stay away.
