Even easier. See the moderators' list of people I am not allowed to swear at and give them a permathread of their own where they can discuss what they like. The title could have a warning that if you are in a demographic that The Daily M*il or Fox, (to cover both sides of the pond) blames for having the audacity to exist, you may not want to open the thread in case you are deeply offended.

If you have a view about history that doesn't accord with recent revision aimed at sanitising mistakes, you might not wish to go on it either, in case you called a liar for disagreeing with anybody subjectively called eminent.

In return, delete anything they spout that is deeply offensive in threads read by respectable decent people.

By the way, swearing at them isn't offensive. 1. They are thick skinned, they have to be to have the views they have in the first place. 2. No point in calling a spade an earth inverting horticultural implement.

In return, I'll stop questioning why we publish incitement to hatred and castigate those who refuse to see it go unchallenged.
