Finally, after classlessly calling me a **** three times, you admit that Islam justifies deceit.
I called you a **** because you accused me of being a liar. You also claimed that Islam unconditionally approves of lying to "infidels", which is incorrect, but not the reason I called you a ****.
However, we have a perfect example of that deceit. Not only does it justify deceit in its preservation, it also justifies it in its expansion.
Oh? According to which sahih hadith or Qur'anic ayah?
Any religious ideology that depends on deceit to preserve and advance itself is weak. Any follower of that religious ideology cannot be trusted to be forthright. It's simple.
If you and I were at war, you'd be correct, and I wouldn't trust you either. If you want to hear me lie to you, point a gun at me.
