Favorite quote from the post:
“(We) have to be careful not to allow this movement to get any legitimacy. I’m taking this seriously in that I’m old enough to remember what happened in the 1960′s when the left-wing took to the streets and somehow the media glorified them and it ended up shaping policy. We can’t allow that to happen.”— Congressman Peter King, Head of the House Homeland Security Subcommittee.
