I don't see any evidence of him being a leftist or a liberal, right now, he is being used as a tool to take away americans rights to self defense, and for that reason, we should support him. Also helping black children doesn't make him a liberal, JTF is not a racist organization, I'd rather those kids look up to a conservative role model than fall into the ghetto lifestyle or criminal world.
Also having a Jewish father wouldn't make Zimmerman Jewish unless his mother was Jewish, his father may have Jewish ancestry based on the last name however.
