myfriend, as a consumer I have the right to discriminate when purchasing items. I can choose where and when to use my money. And I often choose to shop at large department stores over small businesses because they offer better return policies.
What is discrimination is not hiring someone based on their race/nationality/gender. Or not allowing them the same seat on the bus. Or putting up signs that say “No blacks or Jews allowed.” We aren’t talking about the same thing.
