Why Did the Southern Poverty Law Center Include Occupy-Related Terrorists Under 'Radical Right' Header?

On "May Day" of 2012, when the "Occupy" movement and its various offshoots took to the streets to protest corporate greed and capitalism, five men took the protests to another level and plotted to bomb an Ohio bridge.

Two of the suspects listed "Occupy Cleveland" as their employer on their Facebook pages, and according to U.S. District Court records, federal authorities got wind of the plot after infiltrating Occupy Wall Street.

Not only that, but one of the suspects, Anthony Hayne, actually signed the lease for the Occupy Cleveland warehouse.

Why, then, is the well-known Southern Poverty Law Center (SPLC), a nonprofit civil rights organization, linking the suspects as a part of the "radical right"?

Here is a screen shot from the organization's "Hatewatch" page, which says "keeping an eye on the radical right":

The SPLC does not give a clear analysis of why the men are considered right-wing in its article, though it does note the Occupy connections.

The connections, however, are largely downplayed, and the suspects are described as members of the "Revolutionary People's Party," which they allegedly formed after growing disillusioned with the movement that started in Zucotti Park.

But either way-- is the "Revolutionary People's Party" any more right-wing than Occupy?

The American Thinker speculates that "Occupy" and all of its violent offshoots have become a headache for the left, and now the Southern Poverty Law Center has found a solution:

The movement, which received favorable comments from the commanding heights of the American left -- President Obama, Nancy Pelosi, the New York Times, and MSNBC -- has now shown itself to include very violent elements, including actual terrorists...
Perhaps drawing inspiration from Rep. Debbie Wasserman Schultz, who can lie with an utterly straight face about reality...the Southern Poverty Law Center has stepped in to solve the problem for the left. Re-define the Occupy movement as "radical right."

This is not the first time the Southern Poverty Law Center has inexplicably labeled an individual as part of the "radical right." Somehow, historian David Barton, the Ku Klux Klan, the Family Research Council, and Black Panther Malik Zulu Shabazz have all been considered right-wing by the nonprofit civil rights organization.
