i don't get why people hate on this, either. bands think it's cool that you wear their merchandise to shows...hell, it's a great way for them to get revenue, for one. it's just a personal thing. I usually got to concerts alone, and like to chat with other people before the show, in between sets, etc. If someone is wearing a t-shirt of a different band than we're seeing, it's a conversation starter. Obviously we both like the band we're there to see.
