While I was on Recruiting Duty, I was relocated to an office that got vandalized by a bunch of moonbats. (I was in good shape and still into Judo at that time.)Then, about once every couple of months, I had to deal with moonbats protesting different things at the Military Entrance Processing Station. I never had to deal with any outright violence, myself.
A side note.... one of the moonbats protesting was in the Navy Reserves. His trial ended up allowing the flag to be burned as part of the First Amendment. He WAS discharged from the Naval Reserves with an OTH discharge, IIR.
