The term microaggressions is a good word. I think it is a good explanatory for why a secular society less interested in morality than utility can get exercised over major and public ''sins'' but ignore less obvious, underlying, insipid and indeed personal faults.

Lying, petty prejudice, greed, dishonesty and abuse of power are becoming more acceptable and applauded
and we are left with few unforgiveables against which people can stand themselves against and look and feel like saints and people who don't need much moral introspection.
