A lot of good things happened (could add womens suffrage too) but there was also supreme court endorsement of eugenics (Buck v Bell 1927).

Then Woodrow Wilson’s Espionage Act during WW1. In Schenck v US and Debs v US, the supreme court upheld convictions (first for the crime of distributing literature arguing the draft was illegal, and second just for hinting that the US shouldnt have joined the war).
