I think you just have to expect there to be idiots on here and in life generally.
I mean I've had two people this week refuse to accept that I've experienced racism... lol. Yet those same people are outraged and feel their lives are threatened by what someone said on Twitter about their whole race...
You do have to expect it, but that doesn't mean that it should be tolerated. I'm not talking about all the faux outrage that's on the big social networks, I'm talking about systemic content that's posted on these forums - often very eloquently countered and argued against by many forum members here - that's simply allowed to continue to be posted on and on again. Often it isn't a single post, but a pattern from a single or number of posters.
