:::You are still pushing your Original Research claim that somehow "the SPLC's current mission" is really only about criticizing the radical right wing.  You still have failed to establish, from a reliable source, that the political opinions of the writers you cite represent "members of the right-wing and mainstream media."  I think using your anecdotal methods, it would be just as easy to claim that "members of the right-wing and mainstream media" accept SPLC classifications without qualifications.

Also, once you start defending the groups who spread "false propaganda about immigrants and other minorities and spread the kind of paranoid conspiracy theories on which militia groups thrive", then balance requires that the article discuss the specific groups the SPLC identifies and their justifications for those classifications. This is certainly doable, but we need a consensus that this is the direction we need to go.  I notice that you continue to add material to the article without regard to these ongoing discussions.  You really ought to show some good faith and stop that.
