All of you guys who are saying "What is the big deal? This is no big deal!" are so full of shit it is amazing.
This isn't about individuality, this isn't about being who you are, this isn't even about being gay. For a man to wear a dress for a warehouse job is clearly not appropriate....and it is in rural Virginia. Lynchburg isnt the backwoods, but there are parts of Virginia in which he would not have been safe in a dress.
It was bad judgement, at best, and a scream for attention, or worst case scenario the beginning of a breakdown. If you think that this is about clothing,.... you are entirely missing the point. Personally, this would make me seek out and befriend this person to find out where his mind is so that I could try to help him. Either help him be more integrated, or help him through a rough patch, or help him make better choices. Hell, I may need to help defend him to others or from others.
The disingenuous "It isn't a big deal. He is just expressing himself" rings false and sounds pretentious.
