Are you suggesting history existed before I was born?
Do I think that Trump is drawing on the same political tradition by 'othering' Mexicans, LGBTs, Blacks to win political support? Do I think that most of Trump's political constituency comes from the 'base' that the likes of Karl Rove built? Do I think that 'liberal political elites' is a dogwhistle for 'progressive social change I don't like' - you bet.
Edit: By reductio ad 'X' I mean in reference to Reductio ad Hitlerum (https://en.m.wikipedia.org/wiki/Reductio_ad_Hitlerum), which as commenter below points out is actually a bastardization of Reductio ad Absurdum
Not really. Reductio ad absurdum is a common proof strategy.
Sure, Trump has tapped into a certain political current that has long existed in American life (since at least Andrew Jackson), but there are other reasons for his (un)popularity and are worth understanding in their own right.
Looks like I got the literal translation of "reductio ad something" right though. Also seems like the spirit is the same between me and Leo Strauss about how said reduction results in something pat, neat, simple and intellectually lazy. That's what I experience every time someone tries to tie up something interesting & complex with a nice Trump ribbon. It has been "reduced to Trump."
