I would say yes, these historic events still affect our society today. The top reasons that come to mind are that in conjunction with these event, racially based laws were put into effect. And while I haven't researched to determine which are still on the books, I do know that as a country we're pretty bad at cleaning up our laws. Also (and probably more significantly), there was a nation growing up during these events who were taught to believe that what was taking place was good, and "for the protection of everyone." This unfortunately creates a lasting mentality that many may not perceive as wrong unless they have had not only the opportunity to learn to correct it, but also to have been willing allow their thoughts and beliefs to be challenged and corrected.
