It's the insistence that those who aren't blinkered by establishment attempts to sanitise the reputation of those responsible for deaths are somehow liars.

So you believe that the historians are lying to save the "establishment" whose members are so long dead.

Funny how from 1930 to 1970 "the establishment" was fair game for them!
What has changed?

You seem to finally accept that I am just saying what the historians are saying.
Your case is that they are all lying.

Lets us all agree to differ on that.
