It is entirely true that the Islamic Brotherhood is unlikely to bring progress to Egypt so long as it defines everyone according to their religious beliefs.
It is NOT TRUE that the fastest growing religion in the West is Islam. The fastest growing attitude towards religion in the West is basically ignoring all established religions, and to not join any of them. Religions, naturally, do not consider dropouts, agnostics or atheists to even be in the comparison. though they clearly are.
It might be that one specific religion is the only true one, and all the others are in some way inferior, defective or totally unacceptable to God (or perhaps several gods). It could be true that NO religion meets with God's favor, or that God simply does not exist, or does not actually have any role or care about humans. But it is pretty clear that God (or gods) have never managed to convince everyone of the correctness of any single religion, so the sane thing to do is to simply leave the entire religious affiliation out of the equation, with obvious exceptions, like not appointing a rabbi to regulate pork bellies or a Hindu to be secretary of livestock.
This is not so much an internal problem of Islam as it is an internal problem in the Muslim Brotherhood's participation in Egyptian politics.
Islam is rather backward compared with the rest of the world, but The UAE and Qatar seem to have few problems of this sort.
