Actually yes. Because by your admission such a business would never survive. If management did that to any of my coworkers I would quit in solidarity and encourage people not to patronize that business.

Freedom, how does it work?

I think a business owner has inherent rights the same as any employee and if he or she only wants to hire people that they want working for them, honestly, they should be able to. Would I only hire white people or only straight? Nope and have hired many minoriites and gay folks over the years.

Most companies if not all nowadays are at will employment, and employers can fire someone whenever they want for any reason they want. Would I respect a company that was that overtly racist, of course not. And with social media today, a company that was discovered doing that would last about 2 seconds.

So, no I'm not "cool" with owners firing someone because of their skin color, I just think the true freedoms of association that we like to espouse doesn't trickle down to business owners in this day and age.

Sad times that people don't get that this mindset would apply to them too. It's the same reason right wingers get deplatformed. But they don't realize how stupid they sound when you say "MUH GAY CAKE!" Like, you can deny business to everyone or no one, there's no case for any in-between. So, everyone in America should be able to be served or else we go full tribalism.
