For that matter, why should any employer be forced to hire anyone they don’t want to hire? Anti-discrimination laws destroyed freedom of association and gave government tremendous power over our lives and took away our freedom. Only government must be non-discriminatory. Everybody else should be free to hire, do business with (or not), rent to, sell to, etc. on any basis he or she chooses.
I suspect the time is long past for “citizen nullification” on discrimination. Associate with whoever you want, for whatever reasons you want....just don’t tell people you don’t want to associate with why..... It’s none of their business—nor the business of the government—anyway.
