I feel like back in the day, the political spectrum was more narrow and although there were disagreements it was more on how to apply the law, not on if a law should exist at all.
Roe v Wade for example is from 1973. This law was established in my childhood, and as a nominal conservative I support it. Removing it is a radical change, leading to an alien landscape where people are fleeing newly antiabortion states and refusing job offers on the basis of what laws they have to live under. Life, death, and medical care are too fundamental to be left to the states. If you do, then do you really have a strongly knit country?
I’ve digressed a bit, but I think the stakes have changed so people on both sides of the spectrum share little common ground.
