You can't be a fascist and not be bigoted. You can be a marxist-leninist and not as a rule hate minorities. I encourage you to go to lemmygrad yourself, see if you find any hatred of minorities being tolerated there. You just won't.

I can coexist in a space with them, they're not going to start calling for the genocide of minority groups. They will deny that genocides have happened, which to be clear is bad but there's a fundamental difference between "these events didnt happen" and a fascist saying "let's mass murder all the minorities because they're biologically impure". I can coexist in a space with one, with the other my murder or the murder of any other marginalized group is as a rule being outright advocated for.

No matter how hard you try tankies even at their worst are not fascists. To try and equate the two is beyond ridiculous. You can point out that some historical regimes have done a lot of horrible things, fair enough. But ideologically marxist-leninists are not comparable on any level to fascists.

I can not, and will never under any circumstances tolerate the prescience of fascism to any degree.
