I think the world would be in much better shape if we had secular political parties instead of the ones we have now. Both the Democrats and Republicans are both run by Christians. Marxism and anarchism are both generally secular- though they seem to have limits. I think it would be beneficial to get a fresh start. The political system is one area where atheists have not made much progress. People generally feel that the Democrats are the lesser of two evils. I think there is a real sense of urgency here given things like climate change, unnecessary war, lack of access to healthcare, overpopulation etc.
I don’t think the major political parties are run by Christians in any meaningful sense, especially democrats.
It seems the American political climate is undergoing a big realignment right now, so we won’t have to wait long for something new.
