Someone who doesn't choose sides.
"That guy's a fence sitter, he fits in everywhere."

(n.) One who is afraid to have an opinion, and rather, simply points out the flaws of what everyone else is saying. Dislikeable to all. The exceptions are those fence-sitters that really don't give a shit and make fun of everything, who are liked by all.
