The disagreement has nothing to do with making Christmas inclusive of other religions (which is a ridiculous notion anyway), so the pastor is missing the point. Arguments are about using public money and public locations to put up religious decorations and statues for one particular religion. No one stops individuals from celebrating, but if a town uses taxpayer money to celebrate Christmas, they should also celebrate all other religious holidays too. But they don't. The Constitution says the government cannot sponsor one religion over another, so when a town council chooses to spend money on a Christian holiday, even if most of the people in town are Christian, it's going to cause dissent.
