Sorry, but I am not going to take a poll of the passengers to see who suffers from what issues before choosing my evening attire. What if the person who assaulted someone was wearing a tuxedo at the time of the crime? Or perhaps they were wearing a bathing suit?
If I decide some time to wear my Marine dress blues, or my Navy dress uniform (double service veteran) on a cruise, I am going to do it. I know many who had or have PTSD and other issues from Vietnam and more current wars. They would never tell someone to not wear their uniform.
