The Gov shall not prohibit any form of religious expression.
Historically incorrect. Mormons were not allowed to practice polygamy, in order for their state of Utah to be allowed into the USA. Islam preaches and practices polygamy.
More over religions that practice human sacrifice, are not allowed to be practiced in the USA. Islam preaches and practices human sacrifice, as their doctrine says that they must convert or kill, as human sacrifices to their filthy, bloodthirsty god allah, all non muslims. More obvious, muslims have their own legal code, sharia law, that is clearly unconstitutional.
Islam should be illegal in the USA, and if crooked politicians, such as the Bush and Clinton families, among others, didn't get paid off by the raghead scum muslims, islam would rightly be illegal in the USA.
