To be honest, most folks have yet to study strict gender identity crises under the "genetic microscope". Yes, there are genes and mechanisms of gene regulations that are gender stratified. Mutations in these areas of the chromosome is massive. So we usually are not talking about a fully independent adult. There are also nuances of genes that seem to be inherited gender-specifically. I think I just read a Science or Nature paper that if the epigentic inheritance was given from Mother to Offspring (be it male or female), then this gene pattern arises. Moreover, we are also beginning to scrape the surface of microRNA regulation and silencers.

Should this transgendered person write their invasive surgery off as a medical expense?

The amount of surgery required and the invasivity of it--meaning the fact that is person elected to have it and by the mere surgery, if there were complications, could have died from it--suggests no matter how cosmetic we think it was or if it was elective, the person should be able to write it off on his/her taxes.

Basically, should the IRS be making ANY medical/clinical decisions and are they qualified to do so?

They can hire outside contractors to decide. But it should be of the person's choosing or at least 1-2 contractors in a collective group.

But, I am VERY uncomfortable with the IRS probing into my medical personal life. That is a HIPPA violation.

Medicine does NOT judge... We are losing that aspect about US Healthcare.
