I assume you meant that as in the burger joint were using it as a pejorative toward blacks, and I call poppycock, as skin color is purely genetic, people are born that way and they cannot change. Homosexuality on the other hand...Sure. I'd say that would fall under a reasonable man standard and, unlike accommodations arguments, it's requiring you to go and work in what might be perceived as a show of support, endangering your business.
Now how about this one: should a hamburger joint be allowed to post "No N-word Served here!"?
Anyone going to give that a shout out? lain:
I doubt it. So there's the reasonable and the unreasonable and they aren't really about a class of people, but a course of conduct and its impact on a business model.
So a KKK leader would never walk into a deli that was, unbeknownst to them, kosher and and ask them to cater a rally? Because, no matter what they might like to claim, they can't always tell when someone is Jewish.That's another one of those "It would never happen" scenarios.
