>>I've already had the argument of the definition of racist - look it up in the dictionary - that is how one determines how a word is defined.

Yes, sir. So you mean precisely "showing or feeling discrimination or prejudice against people of other races, or believing that a particular race is superior to another."

In that case, can you please look up "race" in the dictionary, since that's key to your definition. Hopefully you'll agree there's a plethora of meanings, some of which might make most prejudice racist.

I know I'm being pedantic, but IMHO there's a real risk that these terms are hurled so liberally that it comes to mean simply that somebody with a different shade of skin was affected, no matter the context.

>> that might be homophobia...but that's a rather ridiculous scenario because it seems unlikely that a Chinese restaurant would be in the business of selling wedding cakes.

Seems to me they're distinguishing Chinese food from gay food. What would you call that?

Another scenario: the same couple goes into the Muslim bakery next door and asks the hijabed shop attendant for a rainbow cake for their gay nuptials. What happens next?
