There is only one goal acceptable in Islam regarding other religions. Everyone will eventually have to “submit to Allah”, or they will have to die. The third option, to be tolerated as “dhimmis” as long as they pay the tax and follow the Muslims’ laws, is only a temporary option until there are no other infidels left but the dhimmis.
So no matter what they may say, their religion simply doesn’t allow for any “peaceful coexistence” with other relgions, not in the long term at least.
I read that while you are considered a dhimmi, any other Muslim can kill you at any time for any reason.
