Is there anything creepy or wrong about wearing your team's Jersey when watching a game on TV at home? Is there anything creepy wrong with employees wearing uniforms while in a video conference call?
I agree. It gives people some sense of self, that they are part of the group. It's a great way to get that warm feeling that you are part of a club, company, religion, whatever. Remember, for a lot of people this is their only real contact with others since everyone else is a part of the "world." They need it. They look forward to it and then later can feel a sense of satisfaction.
It is more of a self-help thing than anything else and then they can mentally masturbate on the loving provisions.
