The fall of the 7 Revelation churches

Today all seven have fallen and are Muslim mosques. Why? Even Ephesus fell and the church in Philidelphia why? Do you have theories? Reading a book on the history of Islam and Christianity and author is getting into this one. I have not yet read his theory but this is probably a book for the seminary student so not a book everyone here would read. Something made them all fall and they got judged. In fact all over Turkey Christianity has fallen to below 0.2 %. Actually counting CATHOLICS the number would be lower. Why? Islam has crushed the cross in this region and I believe the same will happen all over Europe and even America someday.

Surely it would be great to see the Unitarian, american baptists, and progressive churches fall, but Islam would be a bad replacement. Certainly my letter writing would get me beheaded!!!!
