I think the fascists’ fixation on Sydney Sweeney has less to do with the size of her breasts and more to do with her blonde hair and blue eyes. They’re thrilled to have an Aryan sex symbol in the mainstream again. They’ve felt threatened by the suggestion that other types of people can be considered attractive as well.
They also seem to be reveling in the fact that western culture is still superficial and celebrates people for being hot, that physical attractiveness is seen as virtue. Because fascism is an ideology predicated on superficiality, appealing to the most shallow of basic human instincts, they need surface-level aestheticism to peddle their rotten ideas.
Now, let me address the two big elephants in the room. I said I wasn’t gonna talk about her boobs but they’re not entirely irrelevant to the discussion. Skinny women with big tits represent the mainstream ideal of what straight men like, and fascists want to assert that what straight men like is what’s right and true. The cis-hetero male-dominated beauty standard is the only one that should exist in their minds.
In reality, people (straight men included) like all sorts of bodies. But fascists don’t like variety and diversity, they want a singular standard for society to adhere to. They want to reduce the complex and subjective experience of being human into something simple, a lie that’s easy to understand.
I was thinking about this and also those big charts of ‘conservativecore’ films and video games and it’s literally just whatever the person making the chart likes, because as you said the crucial thing is superficiality: there is no underlying reason or rational basis for their worldview or aesthetics, all they can do is take a thing that they personally think is good (based on whatever their arbitrary tastes are) and then claim that thing is the enlightened pinnacle of human culture - and that [whatever it is] needs to be defended from the woke hordes who MUST be desperate to destroy it because it’s good, and their enemies simply hate things that are good, for no reason, because they’re evil.
So they both assume they have a monopoly on liking any random thing that large numbers of people are likely to enjoy, AND they gloat about how conservative society’s tastes supposedly are, not because of the ideological dominance of capitalist rhetoric in all forms of media due to bourgeoise control of the means of production, but because other people like the same things that they like!
