pretty sure "feminism" does have a gender label but ok

It's because they're using it as a fad, or don't actually know what gender is. I've met a few non-binary people who have all become Uber-binary to one gender or another in time. It's odd. They may assume gender is a feeling rather than a way of being. Like, I've asked a lot of people about this - how do you know what it feels like to be male or female? No one has an answer. You can't know, you just do and go with what you feel comfortable with.

If anyone who is trans happens to see this if be interested if they can shed any light actually.
