Well lawns are a waste of energy and other resources so you are correct there.

Also autistic person here - in terms of scents I can't stand strong smells like lavender, and roses. But I do like the smell of cherry blossoms and cinnamon.

Texture also has an interesting effect - there are some textures that gives me fingernails on chalkboard level aversion. But other I enjoy a lot.

Looks. I like boobs, I like butts, I like ladies who take care of themselves without being too skinny or overweight. - proportions matter. I like the look of the rear end of my car, and the fact that it has racing stripes. I like fender flares, but again, proportions matter. In terms of tech, I like copious, unicorn vomit amounts of RGB (I do lighting for my church - one of two things that keeps me at that church, the other being the people there feel like family and are lovely people)

Food. I like most foods, but I have an aversion to watermelon, celery, zucchini and cucumber for the texture as much as taste. I also don't like raw tomatoes if they aren't sauced up in some way (like in a sandwich it needs a helping of sweet chilli) and mushy peas make me want to throw up.

Brutalism

Everyone who likes brutalism should be sectioned-off and forced to live in a town with 100% brutalist architecture. If it doesn't cure them of their aesthetic insanity, at least we'll have finally used segregation for the benefit of everyone.
