I provided evidence that you could in fact be wrong. But until you provide better evidence that I am wrong, you can't say that I am with any credibility.
Oh dear.

Not getting it are you, you said Mulsim/Islam, so I said Christian/Christianity.
You went "aha I have him now" and went on about Christian denominations, thus provong in a flash of brilliance that you were right! Well no actually you did not, because you continued to call it Islam, not Sunni, Shia, Wahhabi etc.

So if we continued to use your reasoning, then I can call it Christianity, which means you are wrong.
