it would probably help to assume an implied "all other things being equal" unless you have a specific unequality in mind that significantly reverses the balance of ethics in some common context.

A good example of such a reversal elsewhere in this thread is the "local butter better than imported vegan margarine made from palm oil grown in clear-cut rainforests" argument.

Personally, I extend that argument further, mostly for health reasons, but I'm not vegan.
