There is a difference between having a legal right to horrible beliefs (something most posters here, I think, support), and having an expectation that those beliefs have no effect on your opportunities when you are seeking a highly public job that impacts millions of diverse people.

Many of those people, myself included, probably don't buy the party line that you can completely divorce business decisions from deeply held personal beliefs.

Would you feel the same way if he'd donated to some far-right group that was against intermarriage between blacks and whites? What about something even more extreme? I don't see how the situation would be fundamentally different, or how your argument that this reaction is "too bad" would no longer apply.
