Sure you can. As the other poster said, it's the difference in refusing to serve someone because they're Jewish and refusing to cater their Bar Mitzvah. This is not a hard distinction to understand.

But a hard comparison to make. What would be the gentile equivalent of a Bar Mitzvah?

I don’t know...a baptism, a confirmation? The comparisons are easy.

The point is that baking a cake for someone who happens to be Jewish or Christian is different than baking a cake to be used in a Jewish or Christian religious ceremony.
