I would say policemen, the same thing as pastors.
I just sent via Twitter this DUFU edition to a couple of DUmmies who are pushing for this censorship on Twitter. Oh, and I also sent via Twitter to the ultimate Twit, the Pittster.
BTW, I'm surprised you don't use Twitter. If used right, it is a great resource. I quickly found out you won't learn much if you just read the Twits posted by your followers. However, by using the search function there, I can get a lot of great useful information. Many Twits have links to web pages. Using search, I was able to locate a couple of DUmmies who were all excited about censoring Fox News at Macy's. You can see who they are since I sent them Twits with the DUFU link. Oh, and I also sent a link to Twit Pittster on Twitter.
Well, they both start with 'P', anyway... :)
