Attack the argument and not the person. Do I need to put it in some Koran-like form?
And skydaddy said it unto the prophet blessed be he, thus sayeth Allah the most merciful. It is far better for a person to attack the ideas than the men who spoketh the idea. For the first leads to reasoned debate the latter is Haram and leads to logical fallacies.
There, that ought to do it. See? I am meeting you halfway. Do you need a copy of basic logic as well?
