>>579078☝️🤓 Lowkey opposition to Halloween, Christmas and holidays in general among some communists and leftists isn't related to "political asceticism", but rather to the tendencies of anti-foundationalism, aufheben obsession, distrust of all cultures of the old world, and the general desire to abolish the current state of things.
Halloween, whether seen in its current mainstream commercialised form, as a religious Christian holiday or as a cultural holiday of Celtic peoples, still falls into the same category as things like Ramadan, Diwali, Chinese New Year and what have you: an arbitrary date with arbitrary practices and aesthetics contingent on some specific culture (that itself may be already dead). It's thus in these peoples' crosshairs.
