I'm not sure I would describe a political party with complete control of all 3 branches of US government as a "minority".

This.

Also it's kinda interesting that a place that doesn't favor conservatives is much more successful than the rest of the world.

Would you make that comment about women and POC? Because they are underrepresented in Silicon Valley as well.

I don't know if I'm moving the goal post here, but as far as I know POC and women aren't per definition known for doing the opposite of what made SV successful (-> not conserving old stuff, but trying new and innovative things)

What evidence do you have to say that liberal => SV successful and not white liberal men => SV successful
