Just because they haven't realized they are trans yet doesn't mean they aren't.

A person who dresses feminine clearly does it because it brings them gender euphoria, cis people don't get gender euphoria from presenting as the opposite gender, so therefore it is more than likely that they are trans.

Being trans is not a choice, if you feel cute in a dress you are more than likely trans, whether you like it or not.

I'd still rather be with a bear than a disgusting misogynistic man who thinks ladies (especially trans ladies) are his personal sex toy.
