such as like this:
The concept of gender identity is said to be real as an experience, (like how theists claim to see god [a claim basically]), but scientifically under-defined, weakly grounded biologically, and sometimes treated as more fixed or explanatory than current evidence justifies.


And the what???
Also center is not a “wing”.
You don’t seem to have any kind of coherent thought with your question.
Basically your question is “I don’t say I agree with right wing views, but…” You just use however instead. But it’s the same thing.
Also transgender is neither an ideology philosophy or religion. So your comparison to Theism is way off.
There’s a huge difference in believing to have a personal experience with the supernatural, and to have a personal experience about yourself.
You can make that claim about a lot of things, even gravity and especially time, nobody understands time, would you deny time exist?
