I strongly disagree, I don't mind some people shooting beyond reason on that topic. Misattributing issues of free speech is common. It is even more dangerous to say it would just concern the government.

But even that pales in comparison with peer pressure and fears about missing something, the main driver of virality on platforms like facebook. Restriction on free speech can be subtle. You just don't speak about it or are compelled to say something specific or face retaliation.

That there is some retaliation if there is someone openly denying the holocaust is a dishonest argument.
