I just did a quick search and his father Elias Disney was an ardent socialist. Walt generally followed a more capitalist walk of life but he was reportedly a Congregationalist Christian which at least from a theological perspective places him in the liberal/progressive camp.
Disneyworld may be fantasyland but EPCOT was Disney's utopian vision for how communities should be.
