People are at perfect liberty to hate blacks, Jews and gays, they are just not permitted to disseminate their hatred or stir up hatred amongst others.
In some respects it might be considered preferable that their hatred is voiced on here where their opinions will be shot down, ridiculed and marginalised rather than on a forum of like minded individuals where those opinions will be condoned, supported and given validity.
No thanks. We are not social workers. How many times do you need someone to shit on your lawn to stop inviting them round? I'd rather these people stick to their neonazi forums where the special branch can monitor them without being distracted by the rest of our witterings.
Edit: forgot to mention - I think NSC is fine, and has improved hugely in the last few years.
