Debate ? Opinions are there to be firmly stated, for the removal of all doubt, especially if they contradict a statement by someone else that one does not like or agree with.
After all , this is pprune ! :-)
Thanks. Now I understand. Same trend in universities and the hard left - if you don’t agree with somebody, don’t give them a chance to give their opinion or, if they do get that chance, shout them down.
I thought the Instructor part of pprune would have been more mature. Schoolboy error as I should have known better.
