That's also been a huge drain on the American left historically too, where you've got all these libertine socdem chauvinists who maybe performatively oppose imperial wars but are most concerned with their own personal safety and their own access to treats. They don't even need to form a discrete fascist bloc because they're already bonded to the American civic cult and its fascism-except-it-predates-fascism-as-a-concept nationalist ideology, all it takes is for them to be told that the outgroup is coming for/infecting their favorite treats and they pivot entirely into supporting the far-right establishment.

That's basically what gamergate did, it scooped up all these chauvinist libertines who previously had been vaguely left of center because it was the theocratic right, the pearl-clutching suburbanite reactionaries, and uptight big-businessmen threatening their treats, and it converted them into frothing fascists by telling them "women are coming for your fun-time treats!"

That's why the formation of any such bloc of self-serving chauvinist treat lads has to be countered and dismantled wherever possible, because they're at best fair-weather-friends who'll eagerly be reincorporated into the establishment, and at worst they're a festering rot that can flip over to fascism at any moment.
