What would you classify as a "religious belief"? Can the moral values underlying the Civil Rights Act of 1964 be proven empirically in ways that the Catholic prohibition on abortion cannot?
What do you mean by "discriminate"? Every rational person discriminates; "Catholics believe these things, but not those things", "Democrats support these policies, but not those policies", etc. Human society wouldn't be possible without it. You of course mean the sort of discrimination targeted by the CRA; and most Christians would agree with you, both because of the Christian concept of spiritually equality before God, and because that sort of animus is simply
irrational. But when you seek to extend the protections of the CRA to human
behaviors, and insist that one mustn't discriminate based on what that person does with other consenting adults sexually, well then you've just placed a massively important domain of human behavior beyond the reach of ethical inquiry, and it's you who is now acting irrationally (especially given the mountain of evidence that
sexual liberalism is rapidly killing the West).
There's no such thing as "freedom from religion". Secular liberalism is no less a religion than Christianity; it's just as totalizing in its truth claims. Good governance is impossible without some sort of shared moral framework among the governed. Protestant Christianity provided that basis for most of our history. The current unprecedented levels of polarization and social atomization are directly correlated to the loss of that basis. We can either agree to give local communities the freedom to largely govern themselves (according to their own values), or we can continue tearing each other apart in winner-takes-all battles over the Federal government. I think the former is the only way we can hold this republic together.
