I'd recommend the recent documentary
What Is a Woman?, as it's something of an eyeopener. While it does come across as somewhat biased, there's more than enough truth exposed that anyone on either side of the debate can see that corporate interests are involved in pushing certain perceptions. Big pharma is making a massive killing (no pun intended, but unfortunately true) from pushing transitioning. Suicide rates are apparently higher in those that have transitioned than those that haven't. Puberty blockers are not harmless and reversible - the most popular treatment is the same drug used for the chemical castration of sex offenders.
The influence of the pharmaceutical companies, and attached monetary incentive for them, is likely why the issue is bigger in countries that don't have a government subsidized health service than those that are funded by tax payers.
I am most definitely in favour of adults making whatever choices they want in regards their own bodies, but the way so called medical professionals are steering minors into irreversible biological changes while getting big pharma kick backs is sick and disturbing.
If we allow children to make such life altering decisions as these then we may just as well have no age of consent or any other age restriction (alcohol, tatoos, etc), because apparently children of any age are responsible enough to make all of their own choices.
Give it a decade and their will likely be massive legal action that makes the Oxycontin controversy pale by comparrison.
