People do it when subconsciously or consciously trying to paint a picture with stereotypes. So if someone wanted to illustrate they were talking about a testosterone filled ego driven 20 something, they might include the term young male manager in their descriptor.
Is it right or wrong? Probably not great. I don't do it. But I get how it happens. Probably not nefarious, just a little tonedeaf.
True -- though when I think about it, I imagine them using a more specific male adjective like "bro" or "dude." "Young male manager" would have triggered a "why are they mentioning male?" and yet "female" slipped under my radar until another comment called it out.
I wonder if that's because you have a stronger stereotype for male than for female in your mind (not to suggest that you use it, just that you have one or are aware of what others might have as their stereotype). I don't have strong generalizations either way but especially not for the term female, which is why I never understood when people got uppety about it to begin with. Now that I understand some people have a negative stereotype attached to their usage of the word I understand why people get annoyed. But it is a bummer as its all so personal and subjective that no matter how careful or sincere you are you could tread on someones toes and convey the wrong message, as I suspect the parent comment has done.
