I think in general people believe that freedom of association in business is a much more limited right than the other freedoms enshrined in the first amendment- particularly regarding not associating with people that you find disagreeable. You cannot deny business to someone because of their race or ethnicity, and generally people think this is a good thing. Legal theories aside, I think people feel that it is unjust when a monopoly or near-monopoly business acts in a manner discriminatory to one group or another.
