I can’t really think of a reason for that as Reddit is hated somewhat equally by “both” sides of the spectrum. It’s just something I find interesting.
Politics aren’t genetic.
But they ARE communal. Where you grow decides 90% of what you believe in.
It’s actually why I disagree with the top comment chain that smarter means more left leaning. I think it’s more that left leaning communities have better education standards and lead to smarter generations. Cause and effect reversed.
What top comment chain? They’re all talking about Reddit censoring leftists, not talking about the intelligence of any faction. The most I’ve seen are people making fun of the right, but that’s to be expected.
This is the thread’s first reply chain if you sort by top:

Federation may make things wonky I guess.
The ability to propagate the politics depends mightily on the success of the community though. It’s sort of the other side of the ‘brain drain’ principle-- if people have to leave the community for educational or economic opportunity, they’re probably not going to be able to reconstruct the same echo chambers.
Even when you see a preserved group within a larger population (think of Chinatowns and Little Italies), they’re inherently getting a lot more cultural exchange than back in the home country.
A lot of the most self-destructive policies (neglecting education, running the environment into the ground, skate-where-the-puck-was-in-1972 economic policy) are just begging for decades of brain drain. The kids are going to leave because there’s simply nothing there but the Gizzard Extraction Plant, and that got automated in 2032.
