You're making a very poor analogy.
It would be more accurate to have a Burger King not sell someone a Whopper because they planned to eat it at the same time as a Big Mac, and BK doesn't condone eating their products in conjunction with McDonald's products. The reality, of course, is that Burger King doesn't give a damn where you're going to eat their food, what you're going to eat it with, or really what you plan to do with it once you've bought it. They just want you to buy it.
The baker, on the other hand, has wedding cakes on the menu. He won't bake a cake for someone because of what they plan to use it for. Most Burger King owners would probably be perfectly happy to sell their food to any wedding that wanted to buy it.
Both, Whopper and Big Mac are burgers. Why BK cant make Big Mac? That kind of burger is not on the menu. Therefore I think there is nothing wrong with "not on the menu" analogy.
Now, I like that you said "because what they plan to use it for", instead of "because they are gays", like the other guy insists. It does matter how you use someone's product and maker of the product can demand how their product is used. I know, some will say, you sold the product, you got money, why do you care, but hold the horses.
Fanuc is well knows robot manufacturer. There was company that bought one of their robots second hand, and decided to have some fun. It was something like this, but not sure are they the guys from the case.
Well, Fanuc did not like how their product was used and forced them thru legal system to sell back their robot. I know it's not the same as bakers case, but I mentioned it because it does matter how product is used.
The thing is the baker objects to how the cake is to be used based on the sexual orientation of the customers. I understand what you are saying, but sexual orientation is still the major factor driving the decision not to sell the cake. If the baker would not sell the cake because it was for a Jewish wedding, I'm sure it would be considered discrimination based on religion, even if you say the issue is how the cake is used and not a problem with Jews.
