In Sinclair Lewis's book "It Can't Happen Here," the author explores the notion that the current global conflict isn't merely a battle between Communism and Fascism. Instead, he suggests that the real struggle lies in the fight for tolerance against the bigotry that both ideologies promote. This perspective highlights a more nuanced understanding of the political landscape, where intolerance manifests in various forms, making it essential to recognize the dangers posed by all ideologies that foster bigoted beliefs.

Lewis emphasizes the importance of unity and acceptance in the face of rising authoritarianism. By framing the struggle as one of tolerance versus bigotry, he encourages readers to consider the values of openness and understanding as critical in combating oppressive regimes. The quote serves as a call to action, urging individuals to challenge not only external threats but also the prejudice that can arise within their own communities, suggesting that true resolve lies in embracing diversity rather than succumbing to division.
