It is disingenuous to suggest that these subreddits are being banned simply because they "attack the left". T_D was banned because of a consistent pattern of rhetoric that violates Reddit's ToS, the most recent cases being outright calling for taking up arms against the government and killing police officers. r/frenworld, r/clownworld, and r/honkler were all banned for similar reasons, being hotbeds of violent white nationalist rhetoric.
