2. Matze's post about banning the accounts of a group of ANTIFA supporters (https://imgur.com/WaAMEyn). This image was linked without any context (perhaps because Matze posted this without any context) so we don't know why these accounts were banned.
One possible take is that there's a fundamental difference between banning opinions and banning presentation. You could ban spam, impersonations, doxxing, all harassment and insults, posting fecal matter, porn, racial and other epithets, and so forth, but still be able to discuss the related crazy ideas (holocaust denial, child porn legalization, etc). I think this preserves the most important part of free speech.
If you let me ban enough classes of words and images, I can ban ideas. If nothing else, I can ban people talking about those ideas for their awkward attempts to get around the bans on words.
