Reports that Bill Clinton has no problem with this got me to thinking about the morality of partaking of private accomodations that discriminate. As I see it, there are three possible issues:
If you golf at a No Jews or Blacks establishment, are you yourself discriminating by that very act? I would say no.
Are you lending support for the club in it’s practices? I would think that this would depend on whether the club’s exclusionary practices have become an issue or not.
Is there anything wrong with a private person (or club) chosing to discriminate in his associations? This is apparently allowed by the constitution, but may be morally repugnant. Or maybe not. If we agree on Issue 1 that you are not yourself discriminating, and the only issue is 2 - the fact that you are supporting the bigots, then if there is no moral issue in private bigotry, you’re on safe ground.
(This leaves aside issues that primarily affect politicians - I’m wondering more about a private citizen).
