There is a Robert E Lee high school in Florida — shocking enough — which has banned teachers and students from showing support for Black Lives Matter.

I don't think teachers in a public high school can have the right to teach their political views in class, giving them the authority of the school. But they should be allowed to present their views as personal views.

Students too should be free to show their support for a political point, for instance with buttons, shirts, or printed handouts. (I disapprove of making students wear uniforms.)
