Bigkid - yes, I've seen racist, homophobic, Islamaphobic, disablist, etc. comments "below the line" in Comment is Free articles, yes, left to stand. I really don't understand their moderating policy at all. They zap some things, and leave other blatantly bigoted things to stay.
I rarely read the comments from "keyboard warriors" anymore. If you read the mobile version of the site, the comments section doesn't appear. It's better for the blood pressure that way!
