And, Conrad, here is something more to which you might want to give some serious thought:

If you promote the provision a rostrum to someone who campaigns for a system that advocates the kind of atrocities committed by fascists some seventy years ago, and that system then has a resurgence, and as a result of that, the whole thing happens all over again—and again tens of millions of people die as a result—then YOU share the moral responsibility for that.

Think about it!
