Women aren't fully human in the eyes of a significant percentage of men.
I use a wheelchair and I can't tell you how many times I see another woman, make eye contact with her, we both understand that I'm not going to clip her, and without a word the guy she's with will just grab her arm and pull her to the side.
Happens pretty much every time I'm on a train platform, now that I've started noticing I can't unsee it, just complete lack of respect for the agency of the person they think they possess.
