What about freedom of association?
Anybody should have the right to refuse doing business with anyone else for any reason or no reason at all.
Only public entities or monopolies (i.e. public utilities) should be forced to serve all.
In a culture guaranteeing freedom of conscience and the privacy of personal transactions that would be the case. Tragically we do not live in a society that validates personal choice in commercial matters.
We have politicized social transactions to the point that conscience is disallowed as justification for refusing to participate in a transaction when said conscientious objection conflicts with politically correct interests. Thus has a standard of political influence supplanted personal choice.
That disappeared in this country and long, long time ago.
