Case in Point...

[borisp]

Has anyone here actually read the Koran? I hereby offer the "Koran challenge": try to open it five times in a row, each time to a random page, without finding a passage that encourages murdering infidels, or opressing women, etc.

I think you will be astonished at the results.

The most relevant point towards the OP's argument, I think, is that the foundational text upon which the religion of Islam is based is completely and thoroughly flawed. It is a text that is ideal for gathering a mob to wage war against their neighbor, and nothing more.

If one is aiming to attack modern religions for their irrationality, then one needs to appeal to their foundational texts. No more and no less will point out their absurdity.
