Comment: Civil rights have "come a long way" over those 49 years.  For many Americans, attitudes toward Black Americans have changed.  We're still far from perfect, but we're (yes, I'm an optimist) better than we were in 1968.  The "Black Power" movement was part of the Civil Rights era movement toward racial equality.  Some would say it was helpful, some would say, "no, it was counterproductive."

Today, we have more moderate Black community leaders and organizations, along with "non-Black" supporters working for more equal treatment for all Americans...specifically addressing people of color.  We also have Black Lives Matter working for the same goals. The same debate can be made regarding BLM and its tactics.   

IMO, Tommy Smith and John Carlos, like Colin Kaepernick, stepped forward in NON-VIOLENT protest.  I respect and celebrate all three of them. Peaceful protest is, IMO, an honorable action and needs to be respected as such.  Gary Crum
