To say that jesus (christianity), jew (rejection of the new testament) and mohammed (islam-the koran) can 'coexist' is to say that they are not mutually exclusive, their doctrine do not contradict. I find this hard to fathom. I've often observed the tendency for the 'modern', western christian to pick and choose (and in some cases, completely transform) the parts of the bible- the source of their faith- that accord with their own personal prejudices. This new, pc, seemingly liberal fad of combining those three faiths and giving them equal claim to 'truth' is either a case of unabashed theological ignorance, or friendly feel-good atheism.
Christianity, Judaism, and Islam are organized religions. They have strict, documented doctrine and they do not allow alternatives. For instance, Jesus is not reported to have said 'I am one way, one truth, and one life. People can come to the father whatever way they want'. Nor did he finish his speech by saying, 'but that's just what i believe - your faith may be different'.
Many more examples abound, as I'm sure everyone knows.
Tolerating and respecting one anothers differences is fine, but twisting and misconstruing different faiths/opinions isn't fair to those that truly abide by them. Surly peace does not require
uniformity.
