As I have contemplated and studied the sin issue, for over thirty years now, I have come to the conclusion that the real reason that we as professing Christians stay where we are even when called by Jesus to separate from sin and apostasy is because we love our independence. And Satan feeds that love of independence because he is the originator of it and so we are fooled into thinking that we can be independent and still be in the family of God. So naturally then there would be no reason to leave a fallen church because you can be independent of their sin and not worry about receiving any consequences. This is a lie!
