Religion in government is the opposite of religious freedom. It is forcing religious opinions on citizens. Religious tyranny. There should be freedom of religion inside your home. In public you can't use your religion to harm others through discrimination or other means. Christianity has come to be associated with bigotry, intolerance, judgement, hypocrisy, anti-science and racism. Everything Jesus wasn't.
The united states was not founded on the christian religion. That is not opinion it is fact! Treaty of Tripoli. Article 11
"As the Government of the United States of America is not, in any sense, founded on the Christian religion; as it has in itself no character of enmity against the laws, religion, or tranquility, of Musselmen; and as the said States never have entered into any war or act of hostility against any Mehomitan nation, it is declared by the parties that no pretext arising from religious opinions shall ever produce an interruption of the harmony existing between the two countries."
