The koran is an idealogical system same as communism or mein kampf.
Very, very similar. The end results are the same.
And I put forth that it is that idealogical system, and not the printed media in which it is contained, that is the true source of discontent. Does the act of burning a book unlearn the thoughts that created it? Would Hitler somehow not have risen to power had he simply issued his ideology through speeches and propaganda, and never bound it into Mein Kampf?
Explain to me how the hypothetical act of flushing a Koran down the toilet would make the world safer.
