Of course there's a reality you can observe. Lets look at these two factually true observations:

Person 1 sees someone who looks like and identifies as a man. They see a man.

Person 2 sees someone who has a vagina, can bear a child, and was born a woman. They see a woman.

My point was that you can arrive at different conclusions from observing reality by ignoring or arguing away the points that refute you.

You didn't even acknowledge my point of it being the same arguments used by transphobes.

Of course, it's easy to use, because your side is "obviously right". All you have to do is look at "reality".
