While I agree that they tend to indiscriminately include conservative groups in their "hate group" list, they do actually track real hate groups from all over the political, racial, and religious spectrum. Check their web site for the list of organizations they actually track.

I may disagree with some of their choices, but they do actually identify a lot of bad guys for legitimate reasons, and someone needs to do it.

The Anti-Defamation League keeps tabs on groups, too:
