Buckminister Fuller is a minor diety in the Nerd pantheon (he’s no Einstein) so I must leap to his defense. A former Navy man who internalized the economy of ship design, he was more of an engineer than an architect; his main goal was to attack scarcity, homelessness, etc. by proving you could always do more with less. He was certainly Utopian in outlook but you would be hard-pressed to pull fascist overtones from his work. He was more of what we now call a Globalist and was perfectly comfortable with capitalism and individual freedoms.
