President Trump and Speaker of the House Nancy Pelosi sent the internet into a frenzy after this week’s State of the Union address with twin acts of incivility. Before his speech, Trump seemingly declined to shake Pelosi’s hand after she extended it, and, at the end of the speech, Pelosi tore her copy of Trump’s remarks in half.

Incivility in our politics isn’t exactly new: Over the years, lawmakers in Congress have seen canings, brawls, death by duel, and tarring and feathering. So, then, the pair’s actions weren’t the most uncivil conduct on record, but the antics still are not acceptable. In fact, Trump and Pelosi are setting awful examples for their supporters, considering we’re more divided than ever. Some experts estimate that political polarization is at its worst since the Civil War, and childish feuds aren’t helping.
