The most prominent examples of "political violence" in the last decade or so include (but are not limited to) Charlottesville, January 6, the attack on Paul Pelosi, the attack on Gabby Giffords, etc.
I'm not saying "the left" doesn't have its share of crazies, and I condemn them all unequivocally, but there's no room for either side to be high and mighty on violent rhetoric or actual violence.
I'm hoping that at some point tomorrow or in the next few days Biden and Trump can do an event together and try to lower the temperature, or we're going to see a lot more incidents over the next decade.
