Don't you realise the same can be said about many of those categories I mentioned elsewhere in this thread? For sure those communists only are out to topple out liberal democracy, why would we support that? Those AFA-anarchists are only out to do the same using even more violent methods, not shunning anything to create their dystopia, who would want to support that? Why should people who call out for the eradication of all men be allowed to use Peertube? Who wants to watch black supremacist material other than black supremacists and why should they be allowed to use this tool for their nefarious purposes? This list can be made as long as you want, eventually asking why the knitting club should be allowed to spread their racism using Peertube [1].
So, no. Either everyone is censored or no-one is. I vote for the latter, let the law decide what is allowed and keep it at that. If it isn't forbidden, it is allowed.
[1] this is not a joke, see https://www.vox.com/the-goods/2019/2/25/18234950/knitting-ra... where they seriously talk about 'Fiber artists of color' (?) pointing out the 'racism' (?) in the knitting 'community'.
