Walking off is unjustifiable. What about the folk who actually want to see the band? Not to mention you're letting the fuckwits "win" their little lame war.
Apparently Silverchair during Freakshow used toy get alot of bottles etc thrown at them during a set - like every show in the states. The drummer actually had an idea of all three of them playing in plastic domes as a shield. haha. The frontman had to get stitches on a few occasions though.
