Talking with some liberals and liberals-pretending-to-be-centrists I know, the pendulum has already swung too far. To them, too far was Trump 1 or Bush 2 and everything after was justified retaliation/healing. This tells me the modern american has no conception of what normal is.
Afterall, compared to today the US was founded as an ultra-rightwing conservative radically Christian country, and it worked out great. So to me, we'll only have gone too far right if we somehow swing back past the quakers.
