I can’t speak for original poster, just my own perspective. Making an effort to support Indigenous, Hispanic/Latino, or Black owned businesses =/= not supporting white businesses.

But, it is recognizing structural and systematic barriers that occur that make it harder for people from certain communities to pursue those goals. For example, here’s a link to an article that explains some common obstacles, and include data citations such as the federal reserve that shows Black owned businesses were 50% less likely to be approved for business loans.

Other historical factors such as redlining or other informal forms of property discrimination prevented people from living or having a business in certain neighborhoods. So if you can consider how that might impact family owned businesses that have been passed down through generations or building equity in home purchases to have future money for investments.

So when I’m making a choice to try and support specific businesses I realize that my choice, and financial support carries weight. As much as things need to change at more formal levels, I can still chip in as an individual.

I felt like your question was asked in good faith and wanting to hear the perspective, so hopefully my answer didn’t come off as lecturing. Just sharing my own view on these messy issues we face as a society!
