A very right-wing Mastadon server when I first started searching for anyone else on Mastadon in my state (US South East). Scary, scary place.
"The paradox of tolerance states that if a society is tolerant without limit, its ability to be tolerant is eventually seized or destroyed by the intolerant. Karl Popper described it as the seemingly self-contradictory idea that in order to maintain a tolerant society, the society must retain the right to be intolerant of intolerance." - https://en.wikipedia.org/wiki/Paradoxoftolerance
I for one welcome our intolerant of intolerance server admins across the fediverse.
