Abortion is actually a really good example of how your claim is totally wrong. Texas has been completely controlled by Republicans for about 2 decades now, and in that entire time they’ve wanted to make abortion illegal. And yet, the didn’t. Why? Because a federal court ruling - Roe v Wade - prevented them from doing so. No red state outlawed abortion until a different federal court ruling allowed them to do so, even though they didn’t want it to be legal.
If states can and do just ignore federal court rulings as you claim, then why didn’t red states outlaw abortion years and years ago? They didn’t because they had to follow the federal court ruling - just like FL will have to abide by the decision in the lawsuit. It’s literally how our country works.
