Not equivalents. The Aryan Nation--all of them--are openly racist. Muslims--not all but some of them--are openly terrorists. So do you think they're secretly terrorists because not all of them have spoken in open forums denouncing terrorism? What is sufficient condemnatory action which would satisfy you? Should they all sign a pledge and submit it to you for your approval?
Disavowing the violent exhortations of their prophet would be a good start. But then, you'd have to ask them why they call themselves Muslims.
Only 7% of Germans were Nazis in 1940. Moderates are irrelevant.
It's not about "my approval." It's much deeper than that.
