Why You Can't Put Religious Symbols on Tax Payer Owned Land

Here's why you can't put a ANY religious symbols on publically-owned land:

Because everyone pays taxes -- not just Christians. It's tax payer owned land. Tax payer. Everyone pays taxes. Jews, Muslims, Scientologists. You can put anything you want on private land -- not public.

By the way, why don't the same people who push for the cross, or the ten commandments, be real patriots and push for a monument for the Bill of Rights?
