Denial immoral

This is a big call. Perhaps it's correct, but that sort of talk that, to a lay person, looks a lot like suppression of free speech.

Certainly when I read statements like 'the debate is over', 'to disagree is immoral' and 'burn heretics' I get a little skeptical about objectivity. Perhaps there are better ways to refute counter-claims than attempt to shut them down. While scientists may have had these arguments a million times over and are satisfied they've won, the public haven't.
