When I see people (including Muslims) trying to discredit another religion to "prove" their religion is right, I imagine the subject is Advil v. Tylenol.
Is one better than the other? It depends on who you ask.
If Advil works better for you, great!
If Tylenol works better for you, great!
You do not have to be wrong for me to be right.
If you have to discredit someone else's faith to feel better about your own, your current choice of medicine is not working.
