You're citing ad hominem attacks against the ostensible founder of the SPLC. That's still attacking the source, not the specific claim. I'm trying to be as clear as I can:

What has SPLC said about a specific group that you find objectionable. 

I'm not interested in heresay or character assassination. What I'm asking for, very explicitly, is for an example of SPLC making incorrect or false statements about the groups they profile.
