i had a similar incident at my dorm last year. I had a 3'' X 5'' sticker of the Confederate flag on my door. And well that offended someone so i was ordered to take it down by my RA. So before i did i scheduled a meeting with the hall director about it. She said since it was on the door that i had to comply and remove it from the door, but they could not mandate what was in my room. So i went and bought a 3' X 5' flag and hung it in the room and always left my door open. My RA wasn't too excited about the flag but of course he could do nothing about it. A week or two later my hall director came by and said ohh i see you caught my drift
