No, and my other comment below addressed this, so I’ll copy the relevant portions:

When you’re talking about toxicity, there are a couple different areas that manifests in written content. One is toxic behavior, i.e. how you convey your ideas, and another is what you say, i.e. the ideas themselves.

Moderating out toxic behavior is much easier, in that someone being actively rude or advocating direct harm or prejudice is often fairly cut-and-dry. Moderating out toxic beliefs is much harder, because that requires setting a baseline of what constitute a toxic belief in the first place (and even beyond that, an unacceptable to express toxic belief).

Nazism and other rightwing “belief systems” have harming others at the core of their structures. As misguided as it is, Marxist-Leninism doesn’t. I think that’s at least a clear enough line to draw in my mind for why they merit different treatment.

Your hypothetical kind of proves my point, even, because what hypothetical username would be the tankie equivalent of

One of the most annoying parts of dealing with tankies is their refusal to admit any of the USSR’s crimes, which is the dead opposite of Nazis who revel in the crimes of Hitler. One ideology (tankies/ MLs) considers the actions wrong, so they pretend they didn’t happen. The other ideology considers the actions right, so they flaunt them.
