I didn't mention Trump, though liberals did elect Trump. Conservative liberalism is still liberalism; Americans shortened it because, well, they can't really handle big words.
As far as the civil rights act that was a median 40 years after the rest of the world... Who cares? Congrats you eventually, after nearly all other western countries did so, adopted a half hearted version of equality that has, 60 years later, failed to make the demographics included equal.

And you're right, the liberals of the 1930s were more progressive than the liberals of the 2020s in the US...
