Are you saying that having Bible quotes IN one's own work space is discriminating and harassing people? Are you saying that homosexuals are scapegoats? Your points are unclear.
Well, since you brought it up; the only reference to the bible in the article was in the book of Leviticus, and the verse dealing with gays is:
Leviticus 20:13 If a man also lie with mankind, as he lieth with a woman, both of them have committed an abomination: they shall surely be put to death; their blood shall be upon them.
I'd call that 'creating a hostile environment', wouldn't you?
