Actually, a close analogy is forcing a kosher deli to sell ham sandwiches with a milkshake.
They’ll never try to force halal retailers to sell ham sandwiches though.
It's a good analogy only if the Jewish deli sold ham sandwiches to other people but refused to sell to it to the plaintiff. If an establishment does not sell a item to anyone then it can't be discrimination if they refuse to sell it to you.
A closer analogy is forcing a moflake bakery to bake a fag cake. Only the media would never cover the story of some poor dykes getting kicked out of a moslim, goat smelling, bakery.
