On Saturday morning, thousands and possibly millions of Americans are going to take to the streets in the March for our Lives, the protest organized by the teenagers who survived the trauma at Stoneman Douglas High School last month. I will be in Santa Cruz, marching for our lives, my children's lives, and the lives of all who are tired of the NRA putting every citizen of this country in danger to serve gun manufacturers' interests. Fox News is quite upset by the prospect of a march, Tucker Carlson in particular, who has spent more air time slapping the organizers around than most other Fox hosts. On Wednesday's show, Carlson brought a former Army sniper on to gunsplain things to victims of gun violence.
