I am aware that was reported, however the photo was from a reporter and photographer working for the Washington Times, which I presume would rather carefully ensure that a Tea-Partier impersonator would not get into their report. Secondly, the same statement that is on the sign was reportedly carried on FreeRepublic.com, which is like the Washington Times, a staunchly conservative entity.
By the way, if you search Washington Times articles, you will find numerous references to “Tea-Bags” as the symbol of the TEA Party movement. If you go to FreeRepublic.com you will find first that the term “tea-bag” has been completely deleted, and second that self-proclaimed TEA Partiers are calling various members of Congress, including the Speaker “douche bag”. The sleazy name calling seems to be on both sides.
I rather suspect that both my friends locally and the originators of the Tea-bag protest were, as I was, unaware of the sexual connotation of the term.
