The first point is already concerning. Puberty blockers on trans kids has been shown in plenty of studies to have positive impacts. Like I said, political process is political.
https://www.psychologytoday.com/us/blog/political-minds/202201/the-evidence-trans-youth-gender-affirming-medical-careMultiple studies that all conclude some version of "puberty blockers or hormone treatment was associated with better outcomes".
I haven't gone through each of these in detail, but the fact is you can find dozens of studies all showing improvement with hormone or puberty blocking treatment and you have to really dig for ones that find any kind of negative outcome. Usually the results are positive, or not enough sample size to conclude. Negative is extremely rare.
The only real question up for debate is if the risks outweigh the benefits, and in political organizations they inherently skew more conservative due to being based at least in part on public perception. Medical organizations almost universally agree that gender affirming care, including potentially puberty blockers or hormone treatments, are appropriate when prescribed appropriately.
You claim that there is "strong scientific consensus" on the appropriateness of puberty blockers, but when people point out that some western countries ban their use, then it's because conservatives have infiltrated their scientific communities.
