The problem is with the want as some do to call wrong right and right wrong, you can't really allow prejudice to go too far.
In this case denial of service would not be wise since these people are not breaking the law or asking the vendor to advocate a criminal act.
The State is there to tax and moderate the business practice and when they default and deny service, then you have what you have now. US State and local and lesser States end up being defunct in their want to deny service in total.
You can not do biz in USA since they refuse to do so.
It leaves you exposed to all manner of fiat, fraud, fantasy, and folly legal actions against you.
A waste of time.
Tort mongering and God play.
