The Americans who fought against the Francoists in the Spanish civil war faced enormous scrutiny back home for what was later described as “being prematurely anti-fascist.” The state worries about people willing to take up arms to protect their ideals without being told to do so (or what those ideals are).
This is the administration of the same FDR who stayed in power for 4 consecutive terms, which imprisoned nearly 150k ethnic Japanese, most of them US citizens, without any due process, and which executed one of the biggest power grabs by the federal administration. In a way, FDR was much more impudent towards law than Trump, but he was not publicly arrogant or silly, and WWII has been won under his rule, so he is considered a good guy.
