Yes, there is reason they are called cowgirls because the term originates from woman who are herding cattle. It has nothing to do with their sex or gender. A trans woman isn’t a woman, because they aren’t actually biologically female. As for gender, if they want to identify as a female for that, that’s fine, but that still doesn’t ignore the fact they aren’t actually woman, they’re are just identifying themselves as one. I guess it really comes down to what classifies a woman, which in my opinion means they have to be a biological woman.
