What you said is exactly right in a world of ephemeral speech, but difficult to employ in a world of permanent records. Anybody can simply link to the joke and stir outrage, over and over, out of the context of the larger learning process.

The Internet never forgets. It is genuinely unclear how to adapt pre-Internet norms. I would prefer presumption of innocence and of a learning process, that is summary dismissal of one-off out of context situations. But viral content (such a fitting expression!) begs to differ.
