I agree. Also I think a lot of people these days are moving away from pure rationalist vulgar materialism as their sole guiding philosophy and bringing some kind of spiritual beliefs into their lives, which I see as a good thing. for me I found relying solely on the former to be unsatisfying. A lot of people have Anglo enlightenment brain and can't conceive that in all likelihood phenomena exist that can't be explained by our current understanding of e.g. physics or hard sciences. Saying spiritualism is anti Marxist is super reductive and pretty Reddit atheist brained like you say.
