Why are certain dating preferences shamed?

So it's late or early in the morning, and I've been reading on some stuff. I don't rlly know how to name this question or how to explain what i'm tryna say but:

Why are having certain dating standards or preferences shamed at times?
Examples being (ofc they're not everyone's preferences but I feel these are the most common majority):
- wanting someone fit and not someone overweight -> this is such a touchy subject sometimes because people may call you fatphobic or preach that you shouldn't judge others by their weight or that all bodies are beautiful (which they are, beauty is subjective).
- wanting a tall guy/wanting a short girl
- girls wanting guys to have a certain standard of financial status
- guys wanting girls to larger hips
- facial symmetry
- I don't know i can't think rn, it's 2:30 am, but you get the point

While people try to be more open about what's considered attractive. Isn't it quite natural to have a preference for these traits? We're ultimately searching for the best mate to reproduce and have children with (ofc that's different now for some as with modern society, the need to have children isn't quite as important anymore.) therefore like animals do, we become attracted to certain traits such as being fit or having clear skin cause that shows the person is healthy and indicates a sign of good genes. Which in turn can produce the best offspring. Or in history where a more voluptuous female shape was more attractive as it showed the woman was healthy or well-nourished at a time where food wasn't as easily available or plentiful for the vast majority.

Attraction is rlly about producing the healthiest and best genetically offspring in my opinion. Ok i'm not gonna bother expanding on this further, you get the gist of what i mean. I don't wanna go off topic with those who don't want children or certain preferences that have nothing to do with reproduction since i'm tryna keep it simple.
