No, it is a female NT thing to glare (well, at least in the East UK anyway). Women are always giving me filthy looks. I don't glare often, I have more of a kind expression on my face. I only glare if somebody gets in my way, but I know I'm doing it.
When I'm walking to work I am nicely dressed and I smile to a person passing by, and they just glare at me. Whenever I tell somebody about it, like a close relative or my counselor, they always say ''it's probably not anything personal, they might just be pulling a miserable face anyway and happen to continue doing it when they meet your eye''.
Usually men smile back at me though, so that's one good thing.
