Utter insanity.
Why not administer hormone-blockers to the fetus in the womb? Because that is the time when gender identity is set—not later, when a boy perceives that his parents really wanted a girl and acts accordingly.
All embryos start out physically female. Literally, a flood of testosterone surges through the embryo’s body early in development and causes the formation of male body parts (including a male brain). Without that early flood, the embryo remains female. Someone who is born with the Y chromosome but who genetically cannot respond to the flood of testosterone remains mostly female (mostly, because the gonads, which produce the testosterone, do not develop into testes and the individual remains sterile).
What this all means is that gender is physically set during early development, and there is no such thing as a “boy born into a girl’s body” or vice-versa. *That* concept is pure lunatic blather.
They do not start out physically female, they start out undifferentiated. All embryos start out with a "bud" in the genital region that develops into characteristically male or characteristically female genitalia, barring some genetic problem or androgen insensitivity, in which case that "bud" can fail to develop, leaving no external genitalia and no internal genitalia, or it can partially develop with aspects of both male and female, rarely.
Liberals are pushing legitimacy for this particular mental illness because it suits their politics.
As if a man magically transforming into a woman by sheer will and putting on the clothing proves there’s no difference between men and women.
As if a man having major surgery and exposure to hormones proves there’s no major difference between men and women.
This is simply a group to use to bludgeon the traditional sex roles by saying they are optional and irrelevant, as well as pushing greater expansion of the state into every detail of our lives. And it gives them yet another weapon to bash conservatives and the fundamentalist strains of religion with.
