History isn’t one straight line progressing towards a liberal society.
Look how much Americans attitudes have changed between 1980 and today. 1980 was the first time most very religious people voted, they abstained before that at the behest of their churches. Now they dictate policy at every election.
In my family photo album there are pictures from the 20s of a woman called ‘uncle bob’. She dressed in men’s clothing, and had a ‘companion’. This was a rough industrial town, they were working class, nobody cared. It was her business.
This is why politics is important - the moment you think everything is better today than it was in the past, you let other people take control of the direction society goes in - with you sitting back presuming we’re going forwards.
