 In commercial domains, businesses can form, or refuse to form, associations with certain customers through commercial exchanges. A business might assert a right not to engage in certain kinds of exchanges with customers: the Christian owners of the Ashers Bakery in Northern Ireland refused to bake a cake with a slogan supporting gay-marriage. Their objection, they said, was to the message for the cake, not to the customers requesting the cake. By contrast, a black photographer might assert a right to refuse a commission to photograph a Neo-Nazi group that is holding a conference on their views. In that case, her objection would be both to the message and to the customers seeking her services.
