What’s true for liberals may also be true for Christians who think they have social justice covered:

Consider some ways liberals have used their cultural prominence in recent years. They have rightly become more sensitive to racism and sexism in American society. News reports, academic commentary and movies now regularly relate accounts of racism in American history and condemn racial bigotry. These exercises in consciousness-raising and criticism have surely nudged some Americans to rethink their views, and to reflect more deeply on the status and experience of women and members of minority groups in this country.

But accusers can paint with very wide brushes. Racist is pretty much the most damning label that can be slapped on anyone in America today, which means it should be applied firmly and carefully. Yet some people have cavalierly leveled the charge against huge numbers of Americans — specifically, the more than 60 million people who voted for Mr. Trump.

In their ranks are people who sincerely consider themselves not bigoted, who might be open to reconsidering ways they have done things for years, but who are likely to be put off if they feel smeared before that conversation even takes place.

It doesn’t help that our cultural mores are changing rapidly, and we rarely stop to consider this. Some liberals have gotten far out ahead of their fellow Americans but are nonetheless quick to criticize those who haven’t caught up with them.

Within just a few years, many liberals went from starting to talk about microaggressions to suggesting that it is racist even to question whether microaggressions are that important. “Gender identity disorder” was considered a form of mental illness until recently, but today anyone hesitant about transgender women using the ladies’ room is labeled a bigot. Liberals denounce “cultural appropriation” without, in many cases, doing the work of persuading people that there is anything wrong with, say, a teenager not of Chinese descent wearing a Chinese-style dress to prom or eating at a burrito cart run by two non-Latino women.

Resist that temptation to feel good after a vote for the right side of history.
