Er, if you don't block them, 11-year-old trans kids will get the wrong ones. That's what puberty does. At a certain age, your body starts producing high amounts of sex hormones. Blocking them means that these kids won't immediately develop permanent secondary sex characteristics which don't match their gender and would cause then suffering. Surely it is better to block hormones at 11 and then go on the right ones at 16, rather than otherwise needing a mastectomy, facial surgery, vocal surgery, hair removal etc. in later life?
