I sure hope you’re right, but the point is that we just don’t know. Reviews of that evidence have determined it to be low quality: https://www.bbc.com/news/health-56601386.amp Read Cass for more details. I also 110% oppose circumcision.
The fact that the consensus differs so heavily between countries where this topic has become a political issue, and countries where it’s not yet become one (e.g., Germany), leads me to suspect these sources are biased. This applies especially to british sources on this topic. The NHS and BBC have become heavily influenced by the Tories in recent years, so I’ll have to question your sources.
See also masks: we're pretty sure that masks work, but the evidence for masking is low quality.
Anti-trans campaigners also misrepresent the Cass review. The review has said that taivstock (currently the only provider of specialist care to trans children) isn't very good. (Trans children and their families also say that the tavistock is pretty awful). They then say that this proves the anti-trans argument that no gender affirming care should be provided to trans children. But what Cass has said is that care should be taken out of tavistock and new given to new centres across England who will initiate care and then GPs can be allowed to continue that care -- this is a big expansion of gender affirming care for children, and trans people welcome it. It's what people have been asking for for years.
Cass does have some weird anti-trans aspects, but it's certainly not the win that anti-trans campaigners are claiming. And this is a core feature of UK anti-trans campaigning: they're fundamentally dishonest about everything all the time. You should always read the sources they're citing, because they always misrepresent those sources.
