It tells you that even if you take the worst case scenario, roughly half are offended and the other half are not.
So, which half do you please? Or at what percent do you choose?
And BTW: the latest poll (by an equally Left leaning publication the Washington Post, so it is by no means partisan), is 3 months more current than the one you quote.
I find it offensive that the Redskins would cave to such pressures, because it won't be the end of it.
Like I said: we've become a society of snowflakes that has to have things changed to suit the latest PC, or we have a hissy fit.
