For me, SPLC had its moment in the sun with the lawsuit filed against the KKK. Even with that notch in the SPLC belt I remained suspicious and viewed their data with a great deal of skepticism.
At least one, of my good friends in Law Enforcement, got taken in by the SPLC. He has since seen the error of his ways. I feel obliged to run stories like this, not as a cautionary tale, merely to say “I told you so!” DOD-drops-SPLC-from-extremism-training-materials.
