Smear campaign against an individual exercising free speech

Yes, www.mediamatters.org has a right to smear anybody they want, though if they cannot prove it true they could be sued. At the same time, the public has every right to tell them how they feel about it. Well, the best I can do is the person who registered their domain:

from www.samspade.org

This is the registrant of the website. Could it be faked? Yes, but that is a federal felony so we would hope they didn't go that far....
