When I was a member 40+ years ago, there not only was no racism but one of our small group was black.
Like many political organizations, the JBS failed to adjust to the end of the Soviet Union.
Once there was not a Soviet threat, all the penetration of our government by communist sympathizers became moot.
I personally salute the JBS for a job well done. They need not apologize to anyone for their efforts—least of all the false accusations of being racist, fascist or mentally disordered.
And yet, one could argue that the corrosive fruit of their mission is tearing our society apart to this very day.
Also, the Soviet threat was reorganized, not removed.
