There is no limiting principle on leftist fury.

American politics is taking a dangerous turn. Or, I should say, American politics is taking a dangerous turn again. In the space of a few days last week, leftist protesters individually targeted trump aide Stephen Miller, taunted Secretary of Homeland Security Kirstjen Nielsen in a restaurant and at her home, mocked (and allegedly spat at) Florida attorney general Pam Bondi at a movie theater, and denied service to Trump press secretary Sarah Huckabee Sanders at a restaurant in Lexington, Va.

Then, on Sunday, Democratic congresswoman Maxine Waters said this:

Make no mistake, this is provocative rhetoric. Angry, in-your-face confrontations dramatically increase the chances of violence. Put people in close proximity, yelling and spitting, and public officials will rightly start to fear that they’re in physical danger. While millions of Americans don’t remember that a Bernie Sanders supporter last year tried to assassinate a significant portion of the GOP Congress, you can be assured that not a single Republican in Washington has forgotten. They can never be sure that the screaming person in front of them doesn’t mean them physical harm.
