I love to cruise, I have cruised enough that I dont even have to run out and buy anything to wear.
I love to dress up. I dont do it in my everyday life so when we cruise I enjoy it. But that is just me. I do what makes me happy. the person sitting beside me in a nice pair of shorts and and a nice shirt doesnt bother me in the the least. but that being said, it is human nature, (or just stubburn people) that will push it to the limit. I certainly hope carnival will encourage the offender to dress more respectfully. that is my only concern with the shorts policy.
I also think the shorts are a sign of the times. Its that way everywhere.
