Your perspective strikes me as a modern version of the old “concern” that talking to teenagers about homosexuality turns straight kids gay. By now we hopefully all understand how that’s just bigotry, and your argument is basically the same. You make some vague allusions to confused teenage girls being vulnerable to gay^H^H^H trans propaganda based on purely hypothetical worries. Gut feeling all the way down.
Note also that your concern is that a straight teenage girl gets mindwarped by the evil trans lobby and not the symmetrical scenario of a hypothetical teenager daughter that is trans but feels unable to come out of the closet because she doesn’t trust the adults in her life to respond reasonably.
Maybe ask yourself if you would be disappointed if one of your kids turns out trans and then ask yourself why.
