Quite, Ellipsis.
Any argument that relies on only presenting half the story, however accurate that half may be, is clearly misleading because of what it omits.
For example, why was Egypt Christian? It wasn't before, being of course... well, Egyptian. Then the Romans came along and first conquered the country before then converting it to Christianity later.
Meanwhile, the religious balance in Pakistan, at least in the modern sense, was determined not so much by Muslims entering and then invading the place, but by the aftermath of British withdrawal from and partition of India. I would have thought omitting that part of the story is also rather obviously misleading.
