So you don't see the irony of people raving about how innately superior they are because of their IQ but hate on people whose core tenant was being innately superior?

"Smart" is very much a function of the work you put in, though of course not the only factor. I don't feel the need to have to explain this more than I have.

Edit: I have to ask... what about the smart people that don't oppose them? What's their deal?

I find anyone bragging about their intelligence to be intolerably obnoxious.

100% of the smart people I know oppose Nazism. It seems there are too many politicians around who are objectively intelligent but are a bit comfortable with at least some of the Nazi Party’s ideas.

"We demand an expansion on a large scale of old age welfare." That's one Nazi Party idea according to Wikipedia (https://en.wikipedia.org/wiki/National_Socialist_Program). I would say you are not that intelligent if you oppose that just because "Nazism bad". If you oppose racism it's pretty clear that you don't in general support Nazism. But opposing Nazism doesn't mean that you even oppose racism, maybe your smart friends just don't like that particular German codified version of racism, it's pretty pointless statement without some analysis. Just like US was back then against Nazism and ultimately even went to war with them while simultaneously being openly racist.

Granted, many of the Nazi ideas revolve pretty obsessively around the concept of race, but looks like at least in one case they were even explicitly not racists: "We demand struggle without consideration against those whose activity is injurious to the general interest. Common national criminals, usurers, profiteers and so forth are to be punished with death, without consideration of confession or race." And that's another idea I basically fully agree with. IMO death penalty should be reserved only for the most serious cases, but society needs to be extremely harsh to career criminals and their ilk, they laugh at lenient punishments.
