First let me say that the young turks are a-holes.
Second, although in this video he didn't act as he normally does, Barry Lynn can be an anti-religion zealot and piss a lot of people off.
That said, Gohmert is an idiotic closed-minded ideologue, that believes not only that his interpretation and beliefs are the only ones that are correct (which is his right and I have no problem with him believing that or telling people about it) but he believes that the US federal government should force his beliefs on everyone else. That I have a major problem with.
No where in the Constitution does it say anything about "separation of church and state." However, two clauses in the First Amendment guarantee freedom of religion. The
Establishment Clause prohibits the government from passing legislation to establish an official religion or preferring one religion over another and therefor enforces the idea of "separation of church and state."
