Yes, of course it is absurd. Only fringe, far-right loonies and Glen Beck would believe such a thing. Actually Russian music is very cool. Very dramatic and suited for a marching band. It also serves as an education for these students. They are there to learn after all. I don't think learning a few things about Russia will turn kids into commies.
The whole circular argument about whose side God is on, whether it's a sports team, or an election, is just nuts. Since the whole argument loses all credibility when the other guy wins. As with the point above,how God must have decided it was and is Obama's turn to be President. But, no, then we get into the God gave man free will, and all that stuff. Just more reason to keep Religion out of politics IMO. Nobody can prove anything anyway. Let everyone pray to whomever they choose, just keep it out of policy and politics.
