Would an organization that publishes information that inspires violence against those it disagrees with be a hate group? I suppose that might be a reasonable qualifier.
Do you remember the shooting at the Family Research Council last year? The perp now says that he was inspired to do it because the Southern Poverty Law Center listed the FRC as a “hate group.” The FRC opposes gay marriage, you see.
I don’t recall anyone saying that they had attacked anyone else because of what the FRC has said. That can’t be said of the SPLC. So, who are the haters?
