I agree that radical Islam isn't a way to get what people want or need, and that Christianity and Islam are very different religions.
The thing is, though, that religions, especially Western monotheistic religions, don't focus on getting what you want but on conforming to some divine will.
I think that the "Muslims are losers" argument 1) isn't going to convince anybody who's decided to become a Muslim and 2) may have limited appeal for Christians who aren't focused on worldly success either.
I think I've been pretty clear about my view on the whole thing and I don't think either of your arguments negates it.
