This one gets to me. Not because I liked them that much, but because Justin has always been a dick and I could just write it off as "yeah they were a bunch of dicks but they put on a good show". An Anti-Flag show in the 2000s, here at least, was one of the few times a punk show wasn't in a basement somewhere, so it was absolutely THE place to be if you were in the scene. They also frequently had great bands with them so it always made for a great time.
But after the accusations came out it left a real bad taste realizing that he's probably much more than "just a dick".
