ok i'll bite and here's my take: i think this weird undercurrent of "socially conservative communism" is mostly coming from the so-called "MAGA communists" and "patriotic socialists" who think that communism can only be for strong manlymen workers that spend all day sweating at the smoke and sparks factory and need to appeal to them. they keep pushing this to separate their reactionary "communism" from standard social progressivism to contrast against your average left liberal and show the MAGA types that "SEE, WE AREN"T LIKE THOSE WOKES".

so in my opinion this is mostly an artificial construct being pushed by some weirdos with outsized influence because they are being funded by the coffers of Larouchites, or as a way to disrupt the increasing radicalization of the younger generations who are finding communism and socialism increasingly appealing (at least as polls seem to suggest). it's a tactic to make them associate communism with social conservatism and drive them back to the center, either being done deliberately or as a byproduct of a different agenda.
