No one gets to declare that they, unlike other people, never hurt children. First of all you are deciding for a kid before they might have a way to express or communicate being hurt in a particular way FOR them that you can't have hurt them and second of all, when they get older have every right to decide if they were hurt by you.
The exceptionalism that somehow the only proper way to be around a child is to be pure and some how only a positive influence is both unrealistic and plays into the exact type of mythology that Christian fundamentalists, fascists and many conservatives dream up which is directly weaponised against LGBT+ people and anyone else considered deviant by hegemonic standards.
The fight isn't who are the real "well adjusted"/healthy/not-fucked-up/whatever people who deserve to be around kids NO! The fight is against the way society is structured such that children are so disempowered that when bad things happen to them at the hands of adults they have no recourse or support WHICH IS THE CAUSE OF THE TRAUMA IN THE FIRST PLACE.
Children are people too and are capable of processing lots of shit.
Once again the carceralist logic of "find the evil person" loses in the face of "empower the disenfranchised". This is how liberation vs reform works, reform can never liberate in this system.
