Majority of us don’t really care, it’s until you decided to make it a means to brand your business as minority owned is you trying to make us care about it. Your product or service is what should be the one speaking about whether your business is worth supporting, not who you support and what community. That’s a huge part of, you know - business. Who you decide to serve or not is another thing but that’s not what this is about.
This opinion looks a little question-begging to me: do all businesses who declare these kinds of things do so as branding? I myself, don’t believe they do as many would be doing so for advocacy for minority groups, for example.
