The second Klan was formally disbanded for tax reasons in 1944, a couple of years before The Clan of the Fiery Cross. I think the argument might be more that the Superman episode kept the Klan from rising again. It was already profoundly unpopular in the war era due to some connections with the American Bund.
I suppose weakening Klan membership at the time of release would be more accurate, I’ll add it to the post
