Hate groups are certainly protected by the First Amendment; see Snyder v Phelps, for example. It's hard to find any behavior on FB that counts as more hateful than that, and they still won 8-1. That doesn't mean FB can't ban them, mind you, since as you rightly point out, it's (mostly) a restriction on government, not private companies.
