The Von Braun center celebrates a WW2 Nazi war criminal. I think that says enough.

Excerpt from the Von Braun Center's About Us page: 

"The Von Braun Center, named for rocket pioneer Dr. Wernher Von Braun, is located in the heart of historic downtown Huntsville, Alabama. This multi-purpose facility is equipped to accommodate major conferences, conventions, concerts, Broadway performances, ballets, symphonies, a full range of sporting events and so much more! Huntsville is a high-tech city with a history of Southern hospitality. The VBC is just a short drive from the International Airport and convenient to area hotels. The Von Braun Center is a turn-key facility with a team of experienced professionals ready to guarantee the success of your event."

This is in no way an attack on the center but a demand that they respect the victims of the Holocaust and people of color, not only in Huntsville, but everywhere.
