"Not all people with brown skin are terrorists" << Nobody said they are BB. If you have to resort to such wilful misinterpretation to make a point then perhaps you don't really have a point after all?
"you WASPs were painting caves" << Now who's being racist?
"its about not generalising religious groups. " << No it's not! Its about fighting terrorists who quite literally want to kill us all!
Unfortunately as long as there are people around who think that the most important thing is to avoid causing offence then we're left wide open. I fear that one day in the near future we'll get e very rude wake-up call.
