I think people simply have to get over their constitutional phobias about this. There is nothing wrong with favoring Christianity over satanism, islam, or atheism. In fact, it is the right thing to do.
If I have a choice between ALL or NONE, I choose NONE, because I dont want to see Muslims praying to Mecca in schools, or worshiping Satan.
If you choose "none", YOU will be left with "none" while muslims, satanists and atheists will be running the country. Want america to be ground down under the heels of islam and atheism? Choose "none".
There is nothing wrong with favoring Christianity over satanism, islam, or atheism. In fact, it is the right thing to do.If you can do it without falling afoul of the Establishment Clause, more power to you. How do you plan to avoid it?
