Have you thought about the practicality of what you're saying? Really?
Think - for what you're saying to be true, a vast global conspiracy numbering billions of people would have to be in seamless operation, with members craftily disguising themselves and masquerading as neighbours and friends, while deviously plotting society's downfall across numerous generation.
Doesn't that just seem a bit melodramatic? Hasn't history taught us that such theories or images are invariably grossly impractical and frequently trumped-up or wrong?
Compare your image, for instance, with what we as westerners know for sure about how people relate to organised religion. Because we're westerners, most of it comes what we know about how Christians relate to their religion. What's regularly been observed is that Christians who are born into their faith frequently just explain away the nastier, sillier, or harder to explain parts of the bible just so they can keep living the way they have been. If you think about it from a psychological perspective, it's really easy to see why that happens and how easily it would and does happen.
Isn't it just more logical to assume that, given that we know this is by and large a very standard thing in organised religions from our own study of our human experience as a civilisation, that it's probably the prevailing trend in Islam too? Isn't it paranoid to assume that anyone you meet who you think might be Muslim (after all, how do you identify one?) is actively plotting your downfall?
