The cruelties to Christians, Catholics, Buddhist, Hindu's, Jews, etc. is after all universal and it comes from one source, the Muslims. It's an internal problem of Islam, as the two factions of Islam are in the throes of massacring one another as well. Unfortunately, blood is the life's milk of this political/religious death & unrest. I know of no other religious belief that requires blood as an entry to heaven.
