There has been a lot written about the similarities and differences between protests in the 60's and present day protests. Unfortunately, subject matter is similar: racism, women's rights, and gay rights. Reaction is similar with riots after killings (MLK, Michael Brown, et al). Marches are similar (Poor people's march, March on Washington, Women's March, Gun control marches). And unfortunately when Trump ordered the national guard to end the peaceful protest march in Lafayette Park, I was reminded of the National Guard killing four students at Kent State for protesting the Vietnam War, memorialized in the song by Crosby, Stills, Nash and Young, "Four Dead in Ohio".
Differences: 60's protests were more limited in real estate. If you didn't live in or near an urban area you might not be aware of what was happening. Social Media was non-existent! Today there are wide-spread protests throughout the country (George Floyd). Also the protests in the 60's were generally associated with a leader, (MLK, Stokey Carmichael, Huey Newton and the Black Panther party, Abbie Hoffman, Gloria Steinman). And protests today are much more ethnically and racially diverse then they were in the 60's.
