Not all men are stupid.

I at one point lived in the same apartment as 5 of them, and have also had brothers my whole life - one brother for the first five years, a second brother since I was almost 5.

Some of my favorite people in the whole world are men.

I have had this discussion many times with female friends and acquaintances.

Some men are smarter than others, of course, and there are stupid people of any gender, race and ethnicity, but that doesn't mean everyone is!

I am glad you added the clarification, yes, that particular man was rude and stupid.
