@DCR it's specifically about this purity spiral phenomen why i wrote about the left only. i don't see this in this way and to this degree with any other group. especially that it's always something new. the current right does things like this as well, but it's limited. maybe they ban books in school libraries in the US etc. they DON'T do things like condemning the stickermule guy for being pro trump and spesking against hate and violence. both camps aren't who i personally like, but the self destructive holier than you thing is pretty unique to the left imho.
