Ed is right. Black Lives Matter.  So do gay lives, women's lives and all other lives.  We should not privilege the sensitivities of one subgroup of a group and throw out the rest.

Who gets to "win" when a person turns out to be complex? Are we going to rename buildings named after President Kennedy because he called the black gay poet James Baldwin, one of America's greatest writers, "Martin Luther Queen"?  What happens to Churchill High School after people read the colonial views of Sir Winston the Tory?  Do we erase MLK's name because he plagiarized a paper?  What did Abe Lincoln think of gay rights?  Did Cesar Chavez support abortion?  

Do people really feel "unsafe" entering a building named after a person a hundred years dead?  That is not a credible position for an adult to take.  The building has only the spiritual power that we each care to give it. 

As for these ancient crusty founders whose lives were imperfect, teach about them, not without them.
