Furthermore, if they are especially interested in the issue, violations of those norms might be more salient and visible to them than for the average person. The person who works in the IRS office sees how frequent and easy it is to cheat on one's taxes. The anti-homosexual preacher sees himself in a world full of gays. The environmentalist grumpily notices all the giant SUVs rolling down the road. Due to an increased salience of violations of the norms they most care about, people might tend to overestimate the frequency of the violations of those norms -- and then when they calibrate toward mediocrity, their scale might be skewed toward estimating high rates of violation. This combination of increased salience of unpunished violations plus calibration toward mediocrity might partly explain why hypocritical norm violations are more common than a purely strategic account might suggest.
But I don't think that's enough by itself to explain the phenomenon, since one might still expect people to tend to avoid conspicuous moral advocacy on issues where they know they are average-to-weak; and even if their calibration scale is skewed a bit high, they might hope to pitch their own behavior especially toward the good side on that particular issue -- maybe compensating by allowing themselves more laxity on other issues.
