Sticking to the facts is exactly the problem here, everyone gets so wrapped up in their moral outrage and presumed superiority that they aren’t looking at what this guy actually said.
This is a problem entirely of his own making, stretching out over decades.
The honest reaction to being forced to recognize that the absurd accusations being thrown at Stallman are absurd, entirely made up, and without any link to what he actually said is not to try desperately to move the goal post.
Stick to the facts.
