At the end of the day, they've had more hit records than all of you and more women too.
They say you're supposed to let insults roll off like water from a duck's back. Well that's fine if you want to be a duck, waddling about quacking all day. This thread is an example of just the sort of malicious behaviour that a policy of appeasement serves to embolden.
If you're a real fan you won't sit still for these sort of insults. The time has come to demonstrate what one determined Def Leppard afficionado is capable of. Then they will fear you.
