Well, we may not see Morris dancing in the Olympic parade, but we have certainly defined the UK's proposal for an additional sport.
It's called "wallowing in our own piety" and we will W I N.
The game runs something like:
"I am more pious than you, because I have thought of a tenuous link between and possible racist activities and I think it might offend someone I've never met and whose opinions I've never sought"
"No, _I_ am more pious than YOU because I have thought of even more tenuous link to something that I think people did 150 years and, if I view that in a 21st century light, I can claim that something done in one context is mind-blowingly offensive to people I don't know, if you put it in a completely different context for which it was never intended."
And so it goes on. Last person standing is the winner. Except there are no winners.
I can understand people making reasonable attempts to avoid actions that might reasonably be expected to cause offense to other reasonable people. That is only fair and sensible. I even try to do it myself. But that's not what's happening here.
I can see the teacher's point of view (remember the teacher?). But it's the sort of thinking - if that's the right word - that's going on here that fuels those fears, keeps the uncertainty and fear going, and pushes people to find offence where it's only to be found by those looking for it.
