The COTUS says what it says. As I said there can be different opinions of how the document should be interpretted; the 2nd amendment is a great example. I too think it's referring to citizens. For example, we treated Indians differently, we treated Mexicans differently after the Mex/US war, etc.
Furthermore, everybody thinks the decisions of the SCOTUS are wrong. Most recently, tons of people (probably a majority) disagree with overturning Roe v Wade. And previous to RvW getting overturned, a bunch of people thought RvW wS wrong.
