No parent wants to take an avoidable, even 1 in a million chance of losing custody of their kids because of doing a reasonable thing that someone could take out of context or make trouble for them about.
Yes because getting your child taken away is a more immediate visceral sort of injustice than (usually unknowingly) damaging their mental health. Most parents would have their kid fucked up than not at all even if the chances of losing your kid are lower. Idk ymmv but that’s what I’ve observed
