If they feel offended because the government isn't endorsing their religion over all others, then maybe THEY should be the ones to get out of the country. Though, I doubt that the majority of Christians, Muslims or Jews really care what the pledge says.
Christian dogmatic hypocrisy at it's finest.
But think about it this way... Do you really want all the Christians to follow all of that horseshit in their book that tells them to stone adulterers, kill witches, and treat women like property?
