I don’t think “female” is offensive.
I thought it was offensive because some (supposedly female) users said it was offensive; but I didn’t understand why my female friends used the term (female).
I found another saying that it wasn’t offensive, and I immediate copied that belief.

I agree. The word is fine, it is how it is used. Like the word male and plural forms of both words. The anonymity shows how people really think of others and perpetuates toxic thinking and treatment of others.
