Every leftist website on the internet, for starters.
A name used on progressive blogs to deride intolerant religious rightwingers ("fundies") who use the Christian faith as a flag and front for every one of their nastiest motivations, statements and actions, hiding hate behind professed faith. Basically "jeebus" is a code word for lefties permitting them to mock self-annointed religious frothing biters / ultraconservatives of the social or financial right who advocate selfishness and cruelty (via nutty religious errors) without actually deriding Jesus or Christianity itself which they don't have a problem with. Put alternatively, a person who follows the New Testament loves Jesus; a person who can't wait to take away sick benefits from a dying lesbian because God Hates Fags loves Jeebus. Get the diff?
