Your post is an intentional mischaracterization, to distract from having to address the truthiness of my previous post about the differences between offensive and defensive force.
Anyhow, no, I don't think any person of any race shopping at a store is offensive force, if the business/ property owner has made it clear they intend to do business with people on a consensual basis and they don't care which race a customer is. That would be an instance of a mutually consenting relationship, which is a good thing.
Of course if a business owner said they didn't want to do business with somebody and that somebody forcibly insisted they be served, I'd have some concerns there.
For instance, if a black prostitute refused to service your tiny penis, because of your race, would you force her to serve you or would you seek another more willing service provider?
