this is coming across as intentionally obtuse questioning. Many people, including governments think that adopting specific sexual preferences and identities is wrong and worthy of criminal charges and harassment at a minimum.

Problem is, parents are literally the most likely people to do that

Only if you have a very biased definition of harm.

No, seriously, look up stats on who gets charged with hurting children and you'll see that it's mostly parents. Sure, once in a while there's a pedophile handing out candy from a van, but almost all of the time it's a parent or some other person trusted by the parents to watch the kid.
