Remove tax exemption status for organizations that use their religious influence to further their political opinion.

In Thomas Jefferson's letter to The Danbury Baptist Assc, he stated: "Believing with you that religion is a matter which lies solely between Man & his God...that the legitimate powers of government reach actions only, & not opinions...that act of the whole American people which declared that their legislature should 'make no law respecting an establishment of religion, or prohibiting the free exercise thereof,' thus building a wall of separation between Church & State."
We not only have the freedom to practice individual beliefs but also the freedom not to have the beliefs of others enforced upon us (ie: gay marriage, abortion).
Therefore, any organization wishing to influence political matters with their religious or personal opinions shouldn't be exempt from paying taxes.
