I hear what you’re saying and I’m not saying you were wrong in your usage. The issue I think most women (including me) have is when men refer to us as “females” while not referring to themselves as “males” is that it makes us feel like they view us as not fully human, or like a lesser animal. Problematic people are often trying to feel superior to others, whether via race, class, religion, age, etc etc, and certainly speciesism (is that a word? Autocorrect thinks so) can play a role.

That’s still a bit different than saying “males” or “females.” Using those words as nouns makes it feel like a nature documentary narration.
