1. Suppose you lived in a society with a massive, age-old injustice.  Think slavery.  Are you the kind of person who would staunchly oppose this injustice anyway?

2. Suppose a colorful, feel-good movement advocating a massive, new injustice suddenly became fashionable.  Think communism.  Are you the kind of person who would staunchly oppose this movement anyway?

My guess is that about 10% of people could honestly say “yes” to #1, and about 20% could honestly say “yes” to #2.  Yet it’s hard to believe more than 3% honestly say “yes” to both.  Most of the people who would be righteous with respect to #1 would be gullible with respect to #2, and most of the people who would be righteous with respect to #2 would be dismissive with respect to #1.
