Today we kick Nazis because here is no room for hate and racism. Is this the end or is it the start to kick e.g. transgender or homosexuality in the future?
Nazis can stop being Nazis. Homosexuals cannot choose to be heterosexuals.
no room for hate and racism.
If you break these rules, you get some backlash. I hope trans and homo people get a similar backlash if they commit similar hate and racism.
In summary, these two points make the difference for me. We do not outlaw an unchangeable identity (in contrast to racism, which attacks exactly that), but actions which would be disruptive and detrimental for the community.
