AC/DC have a hard won reputation for being a straight-ahead classic rock and roll band - and their imagery is now a cultural icon.
So looky who's gone and ripped them off.
UPDATE: From an old interview with Angus Young:
Interviewer: Isn't it ironic that political bands can cause real damage, yet you're the ones that parents and teachers are objecting to?
AY: It's easier to take a swing at someone that's singing about sex and rock 'n' roll, but that's all part of life, and it's all in fun. We're not the ones telling people what to do. I don't like it when people tell me what to do--even teachers. When I was a kid in school, as soon as a teacher starting spouting at me, I'd go off to the toilet to have a smoke. I didn't want to be sitting here having to listen to this guy telling me stuff that was no use to me.
UPDATE II: More.
