No, ban all gender transitioning treatments and children should not be allowed to make irreversible life decisions

Suicide is one they can and do make. If a trans kid knows they are trans before puberty, making them go through that puberty is effectively the same as forcing a cis kid to go on trans hormones. whereas puberty blockers are completely reversible and were first used outside of transgender care. It seems like someone who knows nothing about what being trans is should probably not be making decisions around what their treatment is.
