It's always both. It's never either or. Nature certainly, obviously, effect nurture. But Nurture can actually effect nature through sex selection, diet, violence, or behaviors that activate certain parts of the genetic code.

I don't think people are this broken through simple natural outcome without being fully low functioning. Whatever natural problems a Leftist might have, the fact that they are politically rationalizing it through psuedo-intellectualism is indicative that they have the natural mental faculties not to be resentment mongering Leftists, but they chose to go down the bad path.

This is why so many of the low IQ people who barely graduate high school are also conservative. Their mental capacity is so limited that they are forced to rely on social institutions to carry the burden of cognitive load. They rely on tradition, because it is the assembled wisdom of ages and it tends to make the most sense to try that first. The high IQ people have the capacity to actually think through the problem and it's implications. But it's the midwits who are easily bamboozled by fancy words, and think they are verysmart, but are really only capable of rationalizing, rather than deep intellectual (or introspective) thought.
