It has been found that the transgender brain is 'different'--not male, and not female but different. That is quite an acceptable finding. Transgender people deserve acceptance, compassion and respect just like everyone else. But when being whoever you are does not happen as a matter of fact by virtue of being who you are but it involves transforming yourself into Betty Boop through medical intervention and a lifetime of medication, imposing your 'truth' on society as "not a psychological problem" requires a mass suspension of disbelief--a mass indoctrination. And that is just not like being left-handed. Left-handers do not  pretend to be right-handers by cutting off their hands and swapping them.
