Have businesses post the identity of any groups with whom they will not do business. That protects the right of businesses, and allows excluded groups to shun, and move the overall community to shun, those same businesses. Let the market decide. I think the problem will soon disappear.
You think wrong.
The issue has nothing to do with shunning anyone, nor is allowing business a owner to be up front and honest about his or her ignorance and hate a solution.
Public accommodations laws are predicated on Commerce Clause jurisprudence, where government is authorized to regulate markets, including prohibiting acts that threaten those markets, including local markets. The solution you advocate would clearly threaten both the local market and all interrelated markets, and is consequently no solution at all.
Either you failed to think this all the way through or lack the capacity to do so.
Last, its both telling and sad that this is the type of America you and many others on the right wish it live in.
You keep positing this nonsense about markets being threatened because business owners can decide whom they want to do business with.
It isn't true. It's never been true. You've been called on it but repeat the same lie anyway.
Are you stupid?
