Whilst I abhor racism (I'd be a hyporcrite if I didn't), censoring debate is daft as it would kill the forums. Sure I accept and agree that rude and inappropriate comments should be moderated/removed, however, you can't really ban someone for saying "I hate black/white/asian/etc... people" can you? It would set an ugly precendent.
As long as people can have healthy and polite debate then I don't see the problem.
Admittedly if someone goes out of their way to spout trash such as "all black/white/asian/etc... people are this that or the other..." without a reasoned articulate debate I will completely agree that's pure trolling.
I'm happy to take on board criticism, and I will (I speak for myself here, but will of course take it up with the other moderators) endeavour to act better at balancing the debates/arguments into a less controversial style.
However, you need to RTM the comments, and/or email one of the mod team with how you've construed the offending posts and explain how it could be perceived as inappropriate.
Believe it or not, we're here to help and try and improve the forums, not overly moderate them. I admit we have to be tough at times, but they are for containment purposes, I honestly feel that in general this place is quite relaxed.
I'd say saying that I hate someone of a particular skin colour would be banworthy. It's reprehensible and disgusting, and most definitely racist.
