Yeah I agree, a corporation should not only not care, they should be actively prevented from being allowed to make discriminations base on anything outside of whether they can pay or not. If they sense a potential other problem, at worst it should be reported to police or some other governmental authority, it simply isn't their business otherwise.

To me any other viewpoint inevitably leads to abuse of one group or class or subset of society or another. If they are legally allowed to discriminate in some ways, they will seek to discriminate in others, both in trying to influence law changes to their benefit and in skirting the law when it is convenient and profitable.
