I'm convinced that scrotes who love shitting on their girlfriend's hobbies/ interests are doing it as a form of negging. They want you to feel insecure about the stuff you like so that you'll be easier to manipulate. Or they want you to feel indebted to them for being with you "in spite of your cringiness" and less likely to dump their asses if/once more red flags start popping up.
An example of this would be my new friend at work. She's a casual aquaintance, but we're both lovers of Taylor Swift and so of course we hit it off. She's the one person who might be as passionate a Swiftie as I am. However, she recently mentioned to me that her boyfriend is a massive hater who loves to dunk on Taylor's "overrated" music despite knowing she's a Swiftie herself. At least once a week, he sends her some stupid meme about Dumb White Women and their Dumb Hypercapitalistic Obsession with supporting Taylor's rerecorded albums. Keep in mind that my friend is White herself, and she's told him multiple times that the rerecordings feature additional songs that didn't make the cut for the first time around.
And she insists that he's just being playful, but I'm just out here wondering to myself why he's going out of his way to make his girlfriend feel embarrassed and self conscious about something he knows she feels really passionate about. What exactly is "funny" about insulting your girlfriend for her music tastes every chance you get? Like if he thinks Taylor's fans are so dumb, why is he dating one in the first place?
I mean my friends and family have plenty of hyperfixations I personally don't see the appeal in, but I dont make fun of them for it because that's just mean, and regardless of my opinions, those are still things that bring them joy
Ovarit user said it best: putting 'white' in front of woman is now the get out a jail free card for misogynists.
