. . . and in the ardently xenophobic atmosphere of post-World War I America Klan membership soared. Becoming more strident, the group now articulated opposition to "Niggers, Catholics, Jews...dope, bootlegging, graft, night clubs and road houses, violation of the Sabbath, unfair business dealings, sex and scandalous behavior." By 1921, the Klan numbered almost 100,000 members and money flooded its coffers. At its peak in 1924, 40,000 uniformed Klansmen paraded through the streets of Washington, D.C., during the Democratic National Convention. Like a modern political lobby, the group was so influential that many politicians felt compelled to court it or even to join, particularly in the Midwestern states. Senators, congressmen, governors, judges at all levels, even future President Harry Truman donned the hood and robe (though Truman shortly quit, apparently disgusted by an anti-Catholic tirade).
One joins Toastmasters or the Chamber of Commerce because it's the politically expedient thing to do, not the KKK.

Anti-Black, anti-Jew, etc. apparently was OK with him.
You don't join the KKK and then claim victimhood. He knew what he was doing.
The democrat KKK was busy killing Republicans alongside blacks.
