Tombie you are pro'ly right, except those students with good lawyers, suing for PTSD!
Rubbish Bob. It was not a fair question because there was never any need to ask that question of Tombie based on what he actually wrote and the fact he did not reference the previous poster in question.
You were not simply asking Tombie "do you agree with the previous poster" when you wrote "And you think it is a joke?" You framed your question in a way that implied Tombie had actually said it was a joke. Which is why Tombie replied to the effect "Don't put words in my mouth".
About 2 weeks later you're back on the case again asking of Tombie - "Ok. Do you think bomb threats like this are a joke, to be laughed off with a throw away line, " it's been happening for decades?"...
You're simply angling to create confrontation over something that was never actually said or implied in the first place.
