IFR is not the issue, but IMC.
Essentially I am countering the argument that flying in cloud without a RAS in Class G is dangerous and foolish.
The facts appear to be that there has never been a civilian aircraft involved in a mid-air in uncontrolled IMC (whereas tens or hundreds have been involved in collisions in VMC) and that the last time there was a military collision was in 1941, when there were many more aircraft around.
