Being a member of a protected class is not some kind of trump card you can play to get whatever you want from whomever you want it.
Which is equivalent to saying you want to bring back “whites only” or “no gays” signs and whatever else. No thanks.
And let’s be clear. We aren’t actually talking about getting “whatever” from “whomever.” We are talking about people who are members of a group (not by choice) having the right to expect the same treatment as others from a business open to the public.
On the other hand, you have stated, essentially, bigoted owners of businesses open to the public can deny business to anyone who holds this proverbial membership card you mention.
