From this remarkable collection of photos of the Selma-to-Montgomery march:
Here are the people marching for dignity and respect and equality.
Here are some of the white hecklers lined up alongside that march, jeering at the people fighting for social justice.
Nothing has changed from 1965 to 2017, except that the hecklers are now mocking those goals online.
Be like the marchers in Selma. Don’t be like the hecklers.
