"Stop telling people to stop things, Jim"
Virtually everybody has told Keith to stop - on this, on the Famine, on World War One, on Ukraine, on his "real historians in real bookshops".
Unfortunately, none of us have the authority to actually stop him (and those that do seem quite happy to allow him to behave the way he does), but we do have a right to expect to carry on an intelligent discussion without a destructive, hyperactive child nausing it up.
What is boring is your describing as "boring" everything you can't hack - also notable is your tendency to let somebody take the flack for your inability - rather like your officers who were happy to let the cannon fodder go over the top.
You want to take part - feel free, otherwise, mind your own business and get on with your whiskey and soda.
