The anti-fascist label is the correct label to describe a political movement that is against fascists. That is self-evident.
Lmao the anti-fascist label does not have room in it to tolerate material support of genocide, or to justify that tolerance because you need to include those people who support it to serve your other goals.
You're free to call it an 'anti-maga-fascist' coalition if you want. That seems less likely to confuse people who would like to actually act against fascism in all its forms and features, not just the ones that are most immediate to yourself.
