I've not read the koran properly yet, but from d few verses u all have posted, u r only confirming d fact that d koran wants to make Islam seem like the right religion by always criticising and condemning other religions. Y does d koran not focus mainly on guiding its people in the right way or teaching them more about allah? I can bet most chapters in the koran have a statement or two condemning other religions. That alone is enuf to show that y'all muslims r certainly on d wrong path...not to now talk of all the violence it preaches, and d fact that it was established after years of fighting battles.
May the Almighty God guide everyone in the right path and may y'all be ready to accept the truth instead of trying to prove it wrong b4 it's too late.
