You're both right. In some instances their views haven't changed society has. Trans acceptance come to mind, a lot of people decided to draw a line at gay marriage and say that's as far as they'd go. But 30 years prior that was kinda cutting edge progressivism. 

But with things like taxes and policing I think certain people change their minds as they get older and change from an exploratory mindset to a protective one. 

Obviously this is a giant generalization etc etc.

My mom is 68 and getting more “liberal” as she ages. But mostly that means the things that she most wanted to stay the same are things like abortion access, and she’s not willing to vote for anyone who won’t defend it.
