I copied and pasted the answer he gave about Walt and communism, etc. This is what I tried to explain, but this of course is worded better.
Hope that helps!
Q: Can you clear up Walt's involvement with Red-baiting an the anti-communist fervor that swept the country?
A: You might also want to add the accusations that Walt was anti-Semitic. Walt was largely apolitical. He voted for FDR in 1936 then for Willkie in 1940. But in 1941, he suffered one of the great traumas of his life, which I discuss in some detail in the book: his employees struck the studio as a way of getting Walt to accept their unionization. Walt had always perceived of the studio as a workers' paradise and himself as a benevolent leader. The strike shattered all that. Walt was determined not to let his employees have their union, and the strike dragged on for months, until the studio was finally pressured by its main lender, the Bank of America, to reach a settlement. Walt stewed throughout and afterward, and he could only conclude that the strike had been initiated by communists. In this, as I say in the book based on documents I found, he may not have been entirely wrong. From that time forth, Walt was a dyed-in-the-wool anti-communist. He joined the Motion Picture Alliance for the Preservation of American Ideals, an adamantly anti-communist group, and he testified as a friendly witness before the House Committee on Un-American Activities in 1947. (During his testimony he carelessly labeled the League of Women Voters as a communist organizationa charge he was later forced to recant.) As for the anti-Semitism, Walt was certainly no overt anti-Semite. There were Jews at the studio in prominent positions, and there is little credible evidence that Walt harbored anti-Semitic sentiments. But the Motion Picture Alliance was widely regarded as anti-Semitic, and in joining forces with them and allowing himself to be named a vice president of the organization, Walt knowingly put himself in league with anti-Semites, even if he wasn't one himself.
