Still, technologically minded liberals/libertarians, for all their differences, are not the only viewpoints, and even if there's disagreement along that axis it can still lead to a bubble. I doubt you'd see many people on HN advocating for a fundamentally Christian America, for instance.

Yes, liberal-libertarian is only one axis and this axis is different to the Democrat-Republican one. Both liberals and libertarians are socially liberal, as you imply.
