Comparing a football rivalry with the clash of civilizations is a measure of just how shallow the gene pool has become in the religion business. The failure to discern critical differences is a hallmark of incompetence and this screed is no exception.
In fact, as you imply, "tolerance" is not a serious virtue as it tends to blur these critical differences in the service of basically no good end. When will pusillanimous preachers like this UCC phoney focus on the lack of tolerance by the moslem "faith." It does not just burn books(although they have burned plenty of Bibles), it kills people. Maybe the frauds at the UCC ought to consider which side they want to be on after all.
As for Islam being an Abrahamic religion — no way. All of the people who wrote the Bible were Jews. Jesus was a Jew. Whether you are talking about the old or new Testament, you are talking about a tradition that comes from the Jewish people. What was Mohammed? An Arabian pagan who plagiarized the Bible. He even changed the meanings of the Jewish and Christian scriptures.
