A BBC TV personality has been taken off the air due to vague, unstated accusations. They don't say what he allegedly did, only that someone considered it "inappropriate".

"Inappropriate" is not concrete enough to be a valid accusation. It stats a judgment call on which people can disagree.

Thus, my response when someone is accused of "inappropriate behavior" is, "Every accused deserves a concrete accusation, which has a clear definition. No one should be punished for a vague and insubstantial accusation. Those should be disregarded."
