Yeah it's tricky to separate individual items like pumpkin spice lattes or whatever, but "loudly hating things that are stereotypically enjoyed by women" pretty much is just a publicly-acceptable excuse to hate women by proxy. Another example is "deriding makeup and skincare as a waste of time and money". Like it's totally fine if it's not your thing (I find flavored lattes too sweet and can't stand having weird textures on my face) actively hating on it always feels rooted in sexism. You don't find the same vitriol for IPA drinkers or people who are really into shaving anywhere on the internet.
