[MitzaLizalor]

You'd need to eliminate Muda'rat to be sure. Egypt has only been Islamic for a few decades, officially, having been a Coptic stronghold for centuries before if not millennia. Once the inflowing population increased sufficiently, the usual process could gather momentum – as in every other place this cult has spread. Muda'rat is the same as al-Taqiyya.

Tawriya and Muruna are additional considerations. For example by telling me that Muslims are not allowed to lie, which is true, it could seem to me as though I might trust them. Up until I caught them red handed with the silverware, that is, as with any other person. But I am an infidel. An unbeliever, a disbeliever, any other euphemism they come up with: yes, that's me. Therefore, since I am so vile, I do not qualify as fully human and deceiving me is not lying. Having primed me in that way, playacting on demand fulfils my expectations – they think: but I have read their source material.

Then there's Kitman. In my previous example, failing to inform me that lying means deceiving another human being and leaving out the bit about me not being human is a deliberate oversight. Claiming to have been converted but not saying they're allowed to pretend, even required to in some circumstances, is a gaping hole in their communication but for an Egyptian the indoctrination may well only be a generation deep. If so, it's better described as light brainwashing and easy enough to overcome.
