What you said after this is not any more sympathetic.
> Childhood is important but it is not a lifetime, in some ways it is better to check ones ego and just step back and wait.
This is an astonishing display of lack of empathy for the unfairly estranged parent. Not having your child in your life is one of the worst forms of torture a person should not be forced to endure.
> Support the child as ordered by the courts
The courts are, as you said, obtuse and jaded. Not to mention very often biased.
> Accept that and live your best life
You can't, when you're a good parent, you can't "live your best life" if your child was torn away from you.
> after all You don't own the child
I'm trying to be charitable here, because the HN guidelines encourage steelmanning, but comparing "wanting to have your child in your life" with "thinking you own your child" is appalling, to put it mildly. I hope this is just very, very, unfortunate phrasing, because I could find no other way to read it.
> This can be much easier on the child than witnessing constant bickering, accusations and pettiness between the parents.
Being separated from a parent can have even more dire consequences on the child. And there actually are studies on that.
> might be wrong
You argued in favor of the extremely unfair status quo of the courts and tried to suggest it could be better for the child.
