If you call people with vaginas women, you now cross the line for trans folks.
No matter how you phrase it, there will always be someone you will offend. In the case of the word “female” this is driven purely by some folks finding ways to use it offensively, despite it being just as neutral as “women”
Don’t assume malicious intent every time someone uses the word “female” - most likely, they have never put any negative connotations to it and possibly never even heard of this word being used in a negative context.
I mean, if you’re talking specifically in context about people with vaginas instead of women then using the gendered term does exclude both women without vaginas and men with them who are probably a relevant group in that context. But seriously how often does that come up for you? How often is the most important part of the woman you’re referring to her anatomy?
And while “females” is probably just as accurate in most contexts it’s also been poisoned with incel vibes at this point and it’s gonna be some time before it can be salvaged for general use outside of specific biological contexts without sounding like you’re about to unload a whole lot of baggage into the thread instead of getting therapy.
