I am going to go ahead and assume you are not a Southerner, based on that comment. Slavery and abortion have absolutely nothing to do with each other. The only thing they have in common are that they are issues that are divisive and divide the country.
And this actually justifies my position. The reason we have a problem in this country is because legalized abortion is mandated upon all states whether or not the residents of the respective states actually want that. Mandating that abortion be illegal, irrespective of the desire of those states voters, csuses the exact same problems. And in your argument, you further my position that people in different parts of the country believe different things regarding the role of government, thereby making a national imperative improper.
So, you think that if, say, Mississippi wanted to legalize slavery, that would be okay?
By the way, abortion is far worse than slavery. So far, there are about 50 million DEAD since Roe.
