I think worth noting is that Islam places great focus on and energy behind presenting itself as exclusively authoritative, under divine mandate to supercede and suplant all other theologies.
While Christianity, Islam's sibling within the triumvirate (Judaism, Christianity, and Islam) of the Abrahamic mythopaeia somewhat similarly asserts such overarching authority and mandate, it has, at least over the past half millenium or so, been less shrill and violent in pressing the claim.
I do not see Islam itself in negative light. However, in no other wise may be regarded the current efforts of some within Islam to mingle theology and secular authority, seeking thereby to impose their theology by force of law effected through armed militancy. THAT is at once an afront to and an attack upon civilization; it must be not only countered but eradicated.
How can you make these baseless claims when the Quran calls for unification of all the three religions? Answer this question, does any other Bible or Torah call for unification in the same manner that the Quran does?
And please look up the true definition of the word Muslim, it means someone who submits to his Creator - thus anyone is technically a Muslim if he submits in the will of God; whether he's Jew, Christian, etc. it does not matter as long as he believes in ONE God.
Here's the verse:
O People of the Book! Let us rally to a common formula to be binding on both us and you: That we worship none but God; that we associate no partners with Him; that we erect not, from among ourselves, Lords and patrons other than God.
(Surat Al 'Imran, 64)
This is indeed our call to Christians and Jews: As people who believe in God and follow His revelations, let us rally to a common formula - "faith". Let's love God, Who is our Creator and Lord, and follow His commands. And let us pray God to lead us to an even straighter path.
