Good way to find the larger issue Will.   I can't silence the holocaust deniers, but I most certainly an call them the religious/racial bigots that they are.   Unless they act to harm the targeted groups, they don't pass into the realm of criminality.   

Hmm, maybe we could institutionalize them for their delusional thinking?  Nah,  we don't do big mental health institutions anymore do we?  We could put them in the community treatment since mental illness presents no risk to the public.  (yes, I'm teasing Gary -  but he can take it).

Thanks for taking the big picture into question Will.
