As someone with quite a few left-wing friends, this comment was pretty funny to read. I have no idea why people think they can pick apart the inner machinations of the minds of people they've seemingly never spoken to, not into whose ideology they have the slightest insight or interest. Very strong "boomer opining at their suburban kitchen table about the problem with today's youths" energy.
Any given person who identifies as an antifascist is vastly more likely to have deeply sincere & considered political beliefs than essentially anyone else you know in your life.
