One problem with that presumptuous line of thinking:, liberals are not most likely to take our side: any cursory breeze though a history book (or look at the news) will show that they just take fascism’s side while sanctimoniously lecturing leftists.

This is like when liberals complain about leftists “splitting the movement” by daring to have standards. There is no splitting, you are not in the movement. Fedjacketing people for pointing out that genocide enablers aren’t comrades won’t magically make you a leftist.
