Of course, you are correct that this usage implies gender varies based on location, culture, context, time, etc. In fact, this is why it's so useful to have a term for the idea that what's "feminine" in Saudi Arabia is not the same as what's feminine in Inuit culture. I believe that people should be able to evaluate the gender roles of where they are and accept, reject, or define them. If a cis woman wants to shave her head, get buff, wear flannel, get into fights, and call herself a woman then awesome. She's rejected the "traditional" gender roles for herself and made her own way. I would never tell someone the way they experience their own gender is wrong. But I think it's absolutely reasonable to discuss generalizations about gender roles in context and invite people to think about whether they feel like they identify with that role or not.
