Puberty blockers are used on children with precocious puberty in order to help then have puberty at an appropriate time, not to stop them going through puberty. It's entirely different. And even then, they can have awful side effects.
Blockers were originally presented as "time to think" but the overwhelming evidence is that instead of giving a child time to think, they effectively lock them into a medical pathway of blockers, then cross sex hormones. Some also go on to surgery.
This path will not only make many of these young people infertile, it will also make having a functional sex life almost impossible for many, and for some, totally impossible.
Losing all sex drive / desire to have sex is a possibility.
Also, puberty isn't just about genitalia and other sex charactistics, it's also the time when your brain develops from a child to an adult. What affect does pausing that have on a person? This hasn't been researched, beyond some small studies e.g. one which showed brain impatient in sheep, and loads of anecdotal evidence of kids on blockers saying they felt like they had "brain fog".
If the far right were suggesting sterilising gay and bisexual youth, neutering them so they had no sex drive, I hope we would all stand together against something so horrific.
But, can you not see, you are supporting exactly this, but with the magic sprinkle of marketing on top so you think it's ok?
I strongly suggest you go away and read Hannah Barnes' book Time to Think and come back after you've understood what is at stake here.
