Trump mocked over his new design for Space Force uniforms: ‘The evil bad guys from Star Wars’

I really should make this a copypasta, with how often it seems to come up:
No Heinlein was not pro-fascist. That much becomes very obvious if you read, like, literally any of his other books. His politics shifted over his lifetime, but he was broadly an outspoken libertarian, and remarkably progressive for his era.
He explored concepts in his books through the process of writing them. Starship Troopers was one such book. Stranger in a Strange Land was another, started before and finished after Starship Troopers, and presenting basically the polar opposite political ideology.
