Zimmerman's father is white; his mother is Peruvian. This has been reported extensively. (The only ones calling him just "white" have an axe to grind.) Friends and relatives have stated that he was an altar boy; former neighbors say the family was "very Catholic, very religious." I haven't seen any major news outlet reporting on his political affiliation or claiming that he's a Rush listener. (Take that how you will.)
And just because the media lies, doesn't mean that we have to help them. Claiming he's Jewish when he isn't doesn't add anything to the discussion.
