I am not a native English speaker and I have sometimes referred to people as male and female (as that is what I have been taught) but I have received some backlash in some cases, especially for the word “female”, is there some negative thought in the word which I am unaware of?
I don’t know if this is the best place to ask, if it’s not appropriate I have no problem to delete it ^^
Some people think it’s dehumanizing. As an adjective, it’s more acceptable (“There is a female nurse”); it sounds a bit off-putting as a noun (“The nurse is a female”). There are some people who don’t like to use it at all, and that leads to awkward things like using “woman” as an adjective (“There is a woman nurse”)!
You’re probably okay as long as you stick to using it as an adjective, but you still might offend some people.
