With all due respect, I don't think you've offered any kind of explanation here. Why is it more respectful to be dressed up if they are? You've simply restated that it is without explanation. What makes a polo shirt more respectful than a t-shirt? You say there are reasons for the tradition, but you don't say what they are. Traditions may have reasons but they aren't automatically good so it would help the debate to actually know what you thought they were. Note that I didn't say anything to minimize the importance of tradition in general. Nobody is disputing that people do treat each other differently because of how they dress. The question is, what's behind it?
