Tell that to the parents of a "trans" kid, who became trans precisely due to their parents' indoctrination - even if they haven't had surgeries yet, odds are good to great that they've been rendered sterile by the drug-cocktails they are given.
Now, try to convince one of those parents that what they did was to effectively destroy their child's life, and that Gender Ideology is one huge & toxic lie.
Wish you the best of luck.
