Person 1 enters anecdote on a CLEARLY racist incident that occurred. Provides comment to the effect of, "So we are post-racial, if you are white and never experience things like this, you probably do think this is true."
Person 2 blows up the comments with F-bombs and screeds on how SHE was once called a hurtful name for being poor, so OBVIOUSLY things aren't about RACE, and quit calling white people racist! She's proud to be white!
At this point I tried to decide between entering the fray and calmly explaining to Person 2, or going all smackdown on her. Then I remembered:
Vacation was lovely; why did I come back??
