Calling this a 'teachable moment' is really letting the person off the hook for observing and learning up before now.

If he hasn't learned by now what is appropriate behaviour, why do you think he'll ever learn?

And if he doesn't learn rapidly and advance with best practices in corporate culture and governance, then he's not capable of the leadership and management responsibilities of a board member.

The 'teachable moments' were at least 3 years ago, if not much earlier. The firing offence is ignoring them.
