What I find interesting is that shaming someone's behavior is only sexism if that someone is female.
Are you saying what I think you are saying?
What if I am? Why can't a man make an observation about a woman.
Sexist comments are just as likely to offend men as they are to offend women, and men are often at the butt end of the comments. Women aren't more likely to complain about sexist comments, you might just be more aware of the replies. Talk to a broader range of people and you will realize that this is an issue all genders deal with.
