My Marines had lots of politically incorrect conversations. Usually pretty hilarious. But I can understand a black guy not wanting to share a room with a big confederate flag on the wall. The light green corporal should have taken it down when asked.
I would agree. My son also reported that a clerical unit in the same building, but not attached to his regiment, had a dish that somebody would have to put a quarter into if they used a swear word. He said they would have had to place a five gallon bucket in their office.
