That’s a nice tautology you’ve got there. Regardless, looking at people who explicitly say “we are not women” and then saying “they’re women” seems a bit rude and dismissive of their life experience if you ask me. Personally, if a person with a full beard, an imposing physique, and a deep voice says “I’m a man”, I take them at their word. I guess you might ask them to drop their pants to see if they’re really a “woman”, though.
