So you're arguing my general argument is invalid because in the specific example I use, you claim the board is racist. You then go on to claim that social principles aren't interchangeable and public opinion would eventually obliterate them. My question is, if public opinion has always been and always will be anti-racist, how did so many racists get on the board of not just a single company, but the majority of companies in the 70's? Not to put too fine a point on it, but your belief that principles aren't "interchangeable" (I think you meant "changeable" or "subject to change"?) is provably wrong.
