It's clearly against the guidelines to accuse someone of telling a "deliberate lie". None of us can know what they knew or sincerely believed when they wrote that comment.

As I've kept saying I agree that theirs was a bad comment and agree that it should be flagged and killed, but we need you to try harder to avoid personal attacks and escalatory rhetoric like this. You've been here a long time, we value your contributions and tolerate some boundary-pushing from you because we want a broad spectrum of views to be represented, but sometimes we have to say "enough". Please just do your part to make things better here not worse.
