I guess the back of the bus depends on how important you think it is to get where you are going, vs., you know, making some meta-point.
I suppose if Coulter doesn't really have anything worth speaking about and it's all just a ruse to bring up free speech issues, then no compromise will do. After all, if the idea is to get into a fight, there's no reason to do anything other than fight.
It rings hollow and disingenuous to me, if that's what Coulter is after. If showing up is more important than anything she has to say. It's become the American version of soccer hooliganism - no longer about the sport, but about the confrontation.
All part of a $50,000 college education, I guess.
