The concept is real. I've noticed it, but I generally internally call the person a dick a few times and move on. Sometimes not so internally. The ability to "get over it" doesn't mean it hasn't happened. And people over/mis-using the term also doesn't invalidate the concept.

This isn't new, one just gets used to either telling people off, or quietly being upset if something strikes a nerve. It's not like it's just a women/PoC thing, either. I've had to have words with people who've treated younger (white male) crew members poorly just because they looked young. Er, and those over 50, too, now that I think about it.
