Continuation of previous post.

So, let's do a thought experiment, since you seem so fond of them.  We have two wedding cakes, decorated exactly the same way.  Nothing on them indicates any sort of gender of the reciepants of the cake.  Let's just say that they're decorated like this: https://apis.xogrp.com/media-api/images/778ffbbc-9b81-bd6c-5dfe-8d253894aaf6~sc_320.320

One of those wedding cakes is sold to a straight couple for use in their opposite-sex wedding.  Mr. Phillips would have absolutely no problem with that.

The second cake is ordered by a gay couple, for use in their same-sex wedding.  It is exactly the same as the first cake, so Mr. Phillips obviously has no problem with the cake itself.  However, he denies this cake, calling same-sex weddings an abomination.  Now, are you saying that there is no illegal discrimination there?
