You really believe homophobic families are more accepting of transgendered children?
It's weird and it doesn't make sense to me either, but social conservatives seem to be more accepting of trans than of gay. Consider how the Republicans are embracing Caitlyn Jenner.
Pretty insulting to us who've had to deal with bigoted parents, not even mentioning the very high trans youth suicide rate.
Considering the suicide risk, care should be taken before giving kids a drug that increases their risk of suicide. Lupron, the drug used off-label to block puberty, causes depressive symptoms in one-third of people who take it.
