Isn’t there a confusion between free speech and social consequences of opinions? Protection from the second is not a right. Saying something hugely unpopular to a group, no matter the validity of the claim, will generate a strong response from that group. That one group is overly represented for example in Universities is a political problem, not a free speech problem.

If you say something racist in the US, you just get a social (media) outcry. But in France for example, it’s also illegal, so you also literally get a fine.
