The thread was about authoritarians and political strategy but it seems this racist outpouring was waiting for the earliest possible opening. Could have made a thread? Anyway, as for the liberal/conservative stuff you opened with, there is more leeway for racist expression for conservatives, I guess, with policies unfriendly towards immigrants or the disadvantaged, and more leeway for anti-racist posturing for liberals. But I think making a demarcation between racist conservatives and anti-racist liberals is a mistake.
