I don't think it's fair to call the WBC "ultra-right". The WBC is "ultra-whatever-will-piss-the-most-people-off". If they think they can tap into outrage against homophobia, they're homophobic. If they can tap into patriotic outrage, they're anti-American.

I'm sure they're looking, right now, for a way to simultaneously support abortion while denying women the right to control their own bodies.
