Ignoring your example and returning to mine....

If I believed beyond a reasonable doubt (i.e., was on a jury and/or had personally weighed all the evidence) that Pete molested kids, I'd stop buying his music. But it *still* wouldn't change the stature of his art in my mind. It would change only his stature as a PERSON, and hence my willingness to contribute my money to the man.

So, to your example: if I learned of all this evidence, I'd probably stop eating at the restaurant. But any decision I made as to who I pay for dinner wouldn't change the quality of the dinners served.

Fair enough.
