This isn't about religious extremism or morality police, it's about whats best for the individuals. This should be a good thing as it's just an investigation - no ones saying "ban them because the lord said so", they are just investigating, so I don't see the problem. If you are so certain that the science is on your side, the investigation will highlight that.

There isn't much research arguing against puberty blockers because we haven't seen many studies into it yet, it's still a young subject with a lack of science, and anyone who pretends that the science is on their side is either ignorant or wrong. We just don't know yet, but we will do soon hopefully. We even have studies into gender reassignment reversal being turned down because its "potentially politically incorrect". It's exceptionally easy to find the good of puberty blockers in the short term because they do as they say on the tin, and that benefit can be seen immediately.

However, I've also read studies that mentioned bone deposition and height stunting, "standard" side effects (headaches, hot flushes, bla bla), as well as some of the more obvious stuff (increased bullying because kids are little shits, being behind on hormones meaning you develop into an adult later, sterility, etc). There's a few negative stories that have started to come out around them such as this. We may see more of these, this may be an outlier, but the truth is we just don't know yet.

I'm hoping science can figure this out, as there are people that do need help and we apparently have a way to give them time to think, but the science is still at best "experimental", so I'm wary of people that pretend that puberty blockers are a magical fix that should not be questioned or investigated. This is ideologically driven, not science driven. Science waits for confirmations about hypotheses before endorsing them.

While reading up, I found /r/detrans - was a reasonably interesting read. There is still a lot we don't know, and I'm not sure letting people happily go down a path they may regret is not the answer until the science helps us a lil more
