I'm politically the opposite of the person you're replying to, but these two notions are correct and not contradictory. Average people are ignorant and misogynist, and we should acknowledge this and talk about it, but not to their face. If you're not the direct target of the ignorance or misogyny, you should explain to them why their assumptions are false in a dumbed-down way, not using university-level language. Calling people ignorant directly will get them defensive and emotional. They will think they are being attacked because they are a man.

Of course, for people who are directly targeted by the ignorance and misogyny, it's their right to directly call it out, but they might not call it out at all, because they would be targeted further.
