What are actual signs that people perceive you as "Unattractive", realistically?

I've noticed that half of the female encounters out in school or in the street they're d to get either one of 4 extremes

I get a some "LOLS" from woman much older than me on occasion when they see me

MEN on the other hand refuse to be diplomatic towards me & always either want to start some petty fight or argument or look for any weakness they might perceive
