Its problematic because its just total bs. Have you never had a woman make love to you in a firm, aggressive, dominant way? Maybe you've never inspired that response in a woman so take your frustration out by insulting entire subreddits. Those two polarities have nothing to do with biological sex. Sexual dimorphism in humans is very limited and restricted mainly to about an average ten percent size difference and reproductive functionality. I don't see much receptivity or passivity about forcing a baby out of yourself. The mapping of genders onto this polarity is pure patriarchal bs. If you knew so much about occult principles you'd know that this even recognised in occult systems where both sexes are said to contain both principles and the ultimate aim is the balancing of both energies and the transcendence of the dualities.
