At the deepest level a person's identity is just determined by their chromosomes.

All this dumb crap like how a person "thinks" or "feels" is just a bunch of academic mumbo-jumbo made up by liberals trying to make themselves look productive. If you have common sense, then you'll think and feel that you should just accept the role chosen for you by the culture you live in. If you don't accept that your purpose in life is to conform to cultural expectations, it means you think you're better than everyone else.
