Remove the tax-exempt status of religious institutions

While we recognize that churches and other religious institutions are able to contribute beneficially to the society, charity is not the primary purpose of these institutions.
Therefore, religious institutions should be removed from the list of tax-exempt organizations detailed in the United States Internal Revenue Code (26 U.S.C. § 501(c)).
The separation of church and state is a founding principle of the United States; a religious institution should not have any more tax benefits than, say, a research center.
Even aside from this contradiction of principle, many religious institutions (such as the Westboro Baptist Church) do not contribute to society, and instead perform hateful, shows to the revulsion of the rest of the community.
