As one of the unholy trinity mentioned, I would like to speak up for one of us.
I have met Kevin, and I have met and encountered many bullies in my time also.

Maybe it was not quite the correct word to use?
Now as for the other two?
As the comments came from a 'guest', maybe it should not worry us too much? I have had worse..........
