Which of these should be banned for minors?

[Del Tachi]

#1 and #2 definitely.

#3 gets some added nuance because the suppression of puberty in trans youth is not actually an FDA-approved use for Supprelin and Lupron (the most commonly prescribed puberty blockers.)  Restricting off-label use of a drug is a can of worms I'd rather not open; however, I don't believe puberty delay or suppression should be considered best practice for trans youth.  It is important that kids, both trans and cis, undergo the physical and psychological changes associated with puberty to develop a fuller sense of their (gender) identity.   

#4 and #5 are First Amendment issues.  Categorically prohibiting an otherwise allowable, mostly unregulated form of therapy (i.e., "talk therapy" or CBT) on the basis that it is being used for gender affirmation/gay conversion is not a content-neutral regulation of speech.
