I still wear a jacket while flying. To me, clothing is an outward sign of respect to those around you and is very effective when interacting with airport staff. A smile and a suit coat can get you amazingly far when your flight is delayed, cancelled, etc. You are treated differently at an airport when dressed appropriately.
which, in 21st century, is plain wrong. if I go hiking for 3 weeks in Nepal and have only outdoorsy clothing with me, I should be treated exactly same as everybody else. equality and whatnot.
I know it's how we all react on daily basis, everything is evaluated with some emotional context, but that doesn't make it a good behavior and something to be okay with.
