God. One even tries to use Black Swan Theory.. and fails miserably!
Actually, scrolling down, they fill up multiple Bingo cards in the first few responses!
If anyone hasn't encountered TRA logic that is a great place to start.
@Jamdown123 all you need to know is, and I paraphrase a few of those answers, as you are asking that supposed Gotcha! you have a closed mind, are not worth talking to, are dangerous, etc
But this one really caught my attention:
ii) Gender identity is the knowledge of one's own gender, but where does that knowledge come from?
- The same place as proprioception and the knowledge of self. Wherever part of the brain that is.
Proprioception? Now, I taught the basics of that for decades. If knowing where your limbs are at any time is the same as your sense of self then I am in a good position to explain it 
It would mean that your sense of self is more accurate from a distance than it is close up, and, that sense of self will be more accurate when not practised and, maybe more importantly, sense of self would start deep within tendons, muscles, even hair follicles, any part of the body capable of movement... not, as the writer seems to have assumed, in some place in the brain.
To continue the analogy, sense of self would have to have two analagous points of reference (in proprioception ends of a bone, joint, hair follicle etc). So societally that would mean the individual and an onlooker - they would have to agree in order for the sense of self to be understood, in the same way as the cerebellum and thalamus interpret data.
Talking of the brain, cerebellum and thalamus aren't where 'we' live, that's various cortexes - I haven't thought about words like anterior cingulate cortex in years
I could go on...
