Another person outs themselves as our enemy. Believe them. Pay close attention and ask God to remove them asap. I always pray people have a change of heart. But I have to be honest. They don't seem to repent of their wrong doings very often. When we face God, we will be the ones who have to answer if we don't sufficiently protect our children. So, yes, parental rights are ours, as are parental responsibilities. This other person is of no consequence and will be removed.
