“used language I regret”
This seems to be the crux of the matter.
Never, ever lose your cool in a public arena...unless you are willing to suffer the consequences.
Save the rage for the darkness and private environments.
After proclaiming herself to be a Christian, there shouldn’t have been any reason to use language she regretted...no matter how she had been treated/confronted by the other parent. It doesn’t wash...
She’s right on her other observations except for that...
