In theory, almost all faiths should be able to co-exist. Take a look at most mainstream religions. Most have a core belief in letting people believe whatever they want because all paths will converge into one. Even Christianity, though it teaches that Christ is the only path to God, speaks of loving all men and women unconditionally. The only problem is, it is all in theory. It's like communism. It sounds great on paper but when you put anyone behind the wheel you almost undoubtedly will get a chaotic result. Not to say we are inherently evil, but the race of man has a long history of succumbing to pride. Too many times has the pride of a ruler or an important figure shattered the hope of coexistence. I don't know, I suppose the answer in the question would be yes, but it would take a lot of humility.
