Hard-core liberalism, on display at Moveon.org, is indeed a pseudo-religion (Ann Coulter is unhinged, but onto something), and viciously attacking other peoples' faiths is considered fine and dandy if they don't follow the sacred progressive "gospels". By the way, those are an unquestioned devotion to the most extreme forms of pacifism, multiculturalism, Blame-America-First-ism, environmentalism, and nannystate-ism. Lieberman does none of these - a true heretic in their eyes who must be shunned.

The same could be said of the terrorists in relation to non-radical Muslims.
