I don't see how Google adding a black-owned business label might encourage a previously non-racist person to now want to 'fight' black people or feel ill will towards black people.
Putting tags like "Women Owned" de-legitimizes the owner. It makes women owned business seem stigmatized, as if it's unusual or especially notable. It strips them of their dignity.
And considering how many immigrants there starting out with literally nothing (one example) how we should pick one race to help but not all terribly disadvantaged people?
