I used to simply hide pedo threads and didn't exactly fear anything since laws regarding that aren't US tier here, but when the suggestion of them getting their own board was being floated around (which seemed very reasonable), the way it was ignored alarmed me. From that moment on I started paying attention to who were the ones making the majority of posts in those threads and there was very obviously a pattern, which was particularly unexpected given it was from places like the US, and bernds from there would have more reasons to be wary of posting like that than those from other countries.
With that said, although I've recently become more worried about that, it's the number of fags that has really driven me from kc. I have more tolerance with pedos (as long as they don't post nudes) because they're outcasts and all of that, but faggotry is already being shoved in our faces all over the place, I'm not gonna stand that on kc as well. Yeah, there were fags on kc in the past, but I didn't see naked men every time I opened the catalog (more often than I see pedos, even, since at least they concentrate in one or two threads at a time).
