SPLC and ADL - Need to be cross-verified by other reliable sources 

after looking at this page [], I see that other editors are suggesting that since the ADL and SPLC have a 50% approval rating, it should be (though it isn't P ) required that their statements be confirmed by another trusted 3rd party publisher. Is this too much to ask? If so, could that be because there are no other reliable sources who have made claims such as the ones put forth by the SPLC and the ADL? If so, doesn't that mean they are ALL ALONE IN THEIR ASSERTIONS? If so, shouldn't they be considered self-publishing? If so, shouldn't they be removed from Wikipedia because they are making ridiculous claims?
