In this case the stripper made a big deal about it not the Church. The Church did correctly by attempting to get her to turn from her sin. When she was unrepentant they dismissed her and the child because the fact that the woman is a stripper will eventually cause discord in that school.
The fact remains that when a church is forced to ask someone to leave they do not announce to the world why. If the Church did that then I would condemn them for it.
Again I will say that If my mother became a stripper and used that as an excuse in order to put me through school, It still does not chage the fact that she is a harlot.
I don't disagree with anything you say. It is a private church, and they have freedom of association on their side.
