Except of course, the civil rights mandates on private businesses from 1964 have withstood all constitutional challenges.
Of course the vast majority of people have no issues with government saying you cannot discriminate in a business on the basis of RACE, COLOR, NATIONAL ORIGIN, RELIGION, GENDER, or DISABILITY (since the ‘90s). But of course piggybacking the FAKE category of “sexual orientation” (since when does a chosen sexual behavior make you a minority?) onto that laundry list is extremely easy for the courts to do, even though, by default....it automatically discriminates against people of religion.
Just because most Americans agree with the Civil Right Act, it doesn’t mean the act is constitutional. I fully understand that’s where we stand today, but the Supreme Court has rewritten the constitution in virtually every area. That doesn’t make it right, but it is the way things are done these days.
I should add that whenever the Supreme Court tries to act as a super legislature, it simply creates further malfeasance and chaos. If, on the other hand, it stuck with strictly interpreting the law, then we could still join together on issues that have overwhelming public support (like the right of government to force you to do business with people you don’t want) and amend the constitution.
An amendment isn’t easy of course, but it practically guarantees broad support for whatever is passed. It also eliminates a lack of respect for law and continual conflict created by courts who make up the law as they go.
