Well, the original thesis was "that only men like", so enbys are definitely included

I'm not a woman and wasn't claiming to be. People can be only partially female I think there's labels like demigirl and genderfluid which are relatively common and can fit the partially/sometimes female if you want to do further research. (Also Sometimes I do feel rather fem myself)

So enbies can be "women lite" but it's an umbrella term for anyone that isn't just (not meant in a negative way) male/female.

The problem here seems to arise from the assumption that non male people would be women.
