The far-right/neo-fash has numerous platforms that never censor them and will gladly embrace their content: gab, voat, 4chan/8chan to name a few.

I honestly don't see what the big deal is. For example, lots of lefty subs have banished "Tankies", communists who think Stalin did nothing wrong, from their communities.

Ultimately, neither a fascist nor communist can oppose such a purge/restriction without being a hypocrite. Such actions are well within either group's ideological wheelhouse and therefore they should stop complaining.
