If a child is "indoctrinated" into a scientifically correct conclusion (say, Vaccines save lives) is that the same as homophobic indoctrination?
It doesn't need to be exactly the same if it's something that still shouldn't be done
There's enough false information out there without breeding mistrust by constantly saying "because I said so"
The first time anything you're told from someone like that starts to ring false, you start to question everything they told you, including the correct things, and you can't trust everyone to end up circling back to correctness after that trust is broken
