Evolution isn’t just about life on this planet changing. Political views constantly evolve. There was a time when the Democrats were firm believers in slavery and used the Bible to justify their position. Fortunately, Lincoln was a Republican and ended slavery.
As best I can tell, early Liberals believed in a “live and let live” philosophy but of late, Liberalism has become an ideology of forcing people to think and act according to what the “great thinkers” believe.
Now of course, Liberalism must be enforced by law. A good example of that is the former mayor of NYC who all but ruined the pastry business by passing laws to eliminate fat from pastry. Pastry has tasted awful since then.
