Why? My personal buying choices are not a business.
If you believe the consumer has the right not to buy from a business, you should equally believe a business has the right not to sell you something.

Change the law. If you can.
It's the exact same principle. You're fine with discrimination....we get it.

In ways. I can choose whom I allow to participate. I'm not a bit bashful about telling someone it's time they were elsewhere.
