Nope, I am not attempting to silence them. I just believe that if a Presidential campaign is based upon Freedom and Liberty, then accepting donations from Adolph Hitler, or else Osama bin Laden, for instance, sends the wrong message to those with whom we're attempting to spread that message to.
Dr. Paul is free to accept, or deny, their known donations on the basis of that principle, just as they are free to participate in the political process, as well as have freedom of speech, etc.
I just can't fathom sending a "Thank-you-for-donating-$500.00-to-my-campaign" letter to Mr. Stalin is all.
With that said, I do not believe that any terrorist organisation has a "right" to exist in this Country no more than Osama bin Laden should expect that same right. And the KKK Fits the definition of a Domestic Terrorist organisation -- only because of the violent history of that organisation. Now, if the newer KKK members have renounced violence and intimidation (terror) then why can't they find themselves another banner to fly besides that of the KKK?
