Ignoring the fact that the paradox of intolerance is the mother of all slippery slope arguments, letting a fascist speak is not the same as "being tolerant without limit". If your people are turning fascist, it's not because of a clown on itunes, it's because you've failed to provide sufficient education and opportunity to self-actualize to your population. Fascism doesn't grow where fascists speak, it grows where people are hateful and disenfranchised. That's not to say I want Alex to stay. Good riddance. I just don't like the paradox of intolerance.

"I do not imply, for instance, that we should always suppress the utterance of intolerant philosophies; as long as we can counter them by rational argument and keep them in check by public opinion, suppression would certainly be unwise." - Karl Popper
