Am I misinformed or what?

United Methodists, Muslims, form pact in Northern Illinois - UMC.org

I have some strong opinions on the ludicrousness of this but I'd like to hear other's comments. I may be being narrow-minded and I won't cry that "narrow is the path" like the Westboro Baptist bunch but I seriously see flaws in the idea that Christians and Muslims can get together and "agree to disagree". Are we serving the same God as Islam? What about Jesus? What about the anti-semitism of the nation of Islam? What about Abraham being called out from Caldea to separate him from those worshipping the same God that Islam worships? Is this like a dog returning to its vomit?
