They're actually a lot more consistent than this post makes them out to be. If you've got every single thing on their list that makes you a man - from the genitalia, to the physique, to the likes and dislikes, to the sexual orientation, to the behavior - you're a man. Same for a woman. If you're anything less, then they've just found their excuse to revoke your humanity in their own minds. You're different from them, and so now you're lesser than them. The same thing applies to people of different skin colors, religions, etc.
That's how those types of people have always been - they think of themselves as "nice people, but only to those who deserve it" which essentially just means a horrible person to everyone but people exactly like themselves. They honestly believe that any less means they're entirely justified to hate you. All they need is one little thing to point to, and any amount of harassment or worse is "only fair."
While that's true, they still believe you're lesser if you're different. The jewish person in the anti-semetic group and the trans person calling for the end of trans healthcare will still be the first on the chopping block if the goals of those groups come to fruition. They're like pets to them - animals that aren't on the dinner table only because they serve a better purpose alive than dead.
