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. As far the example you're discussing - 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. If they won't serve them at all just because they're gay - well that is a different problem all together.
