(From the annals of miss manners.)
Dear Miss Manners,
Lately, I have come under great stress at work. I extended an invitation to a speaker that most of my colleagues profoundly dislike. He has in the past shown a very authoritarian streak. He relishes in insulting our bosses. He is avowedly a thug, not that different from the people who run this country. The national media hates him, but isn't it precisely the greatest type of publicity a liberal institution like mine wants?
I've started getting all sorts of nasty emails and some of my bosses and friends got upset and started calling me up to find out why I did this. Now the whole world knows about this affair and I can't dis-invite him without making a fool of myself.
Ms Manners, what would you do in my position?
University President in Distress
Just go ahead with the talk and introduce him as a petty dictator.
