I have to disagree. One act supporting genocide of another nation doesn’t a fascist make. Fascism is an ideology characterized by several components, such as racial or ideological purity, focus upon social control through military might, having explicit in- and out-groups, dehumanizing rhetoric, etc.

Biden is a self-avowed Zionist (possibly because he doesn’t really know what that word means), and he was glib in his support for Israel, but you cannot tell me, in good faith, that he has ever demanded ideological purity from his supporters or dehumanized his detractors.

Calling Biden a fascist is an unjustifiably reductive take, and it doesn’t actually do anything but confuse ignorant people into thinking he’s just as bad as Trump, an actual fascist who on Veterans Day called people on the Left “vermin.”
