I think the SC should strike down laws drawn up by state legislatures if they restrict certain rights, yes. Is that considered writing the law of the land? I don’t think abortion and LGBTQ rights have to be expressly written in the Constitution to be federally protected rights.
You can make a pretty clear argument that state makes law saying no gay marriage, SC says that’s within state powers to decide and that gay rights aren’t protected in the Constitution so it’s legal and fine. Doesn’t make it right. We aren’t adding amendments to our Constitution anytime soon due to the fracture in this country.
