This is exactly where this current tyranny is coming from:
The radical leftists who promote it are thereby granted the license to abuse all who oppose them, since those "reactionaries" must be bigots, racist, sexist, transphobes, homophobes - in short: evil people who deserve the abuse of good people like themselves.
Dissidents who reject this new tyranny aren't respected fellow citizens who hold differing opinions: they are evil people who must be silenced. If this trend is allowed to proceed to its logical conclusion, the dissidents will be silenced permanently, by eradication.

A succinct description of cancel culture, the radical left's mob justice that has become normalized.
