Unfortunately where greed, desire for power, perhaps even desire for a justice exists, religion can be used as a tool in various ways. I will not dispute that it can be used wrongly or abused. I don't believe it is interpretation of the teaching of Christ though. Could you honestly read the New Testament and reach the conclusion that you should be doing any of the things you mentioned?

Is football the new religion? I don't think so but possibly it could be misused in one similar way? If for whatever purpose of my own, I wanted to stir up a fight, could I use "your a Man U supporter and he supports Liverpool" to further these ends?
