"... researchers found that a man cannot become a woman by simply "identifying" as one and vice versa."
"Geneticists from Israel's Weizmann Institute of Science discovered certain genes that are only expressed in women, while others are only expressed in men. "
"6,500 genes with activity that was biased toward one sex or the other in at least one tissue, adding to the already major biological differences between men and women."
"Essentially, their research means more than 21 percent of the entire human genome, which is composed of about 30,000 genes, are based on sex -- something a sex change operation and hormones cannot replace."

"Dozens of genes with no direct association to reproduction were also identified as sex-specific. Many of these genes are expressed in skin tissues, are linked to hairiness ... , and are likely involved in hair dimorphism in women and men. Other non-reproductive genes do not seem to share common features with each other, but are each interesting on their own, for example, the moderately men-specific growth hormone GHRH and the men-specific calcitonin-related polypeptide alpha (CALCA) ... The latter is involved in calcium regulation and functions as a vasodilator ... The genes for both seem specific to adult men, although they are related to apparently general biological processes."
Since it is not possible to change your gender, all that transgenderism does is put on a disguise regarding the true nature of the person, but like all lies, it is incomplete.
"Do not lie to one another, since you laid aside the old self with its evil practices, and have put on the new self who is being renewed to a true knowledge according to the image of the One who created him -- a renewal in which there is no distinction between Greek and Jew, circumcised and uncircumcised, barbarian, Scythian, slave and freeman, but Christ is all, and in all" (Colossians 3:9-11).
