Consider a very different case: Suppose I’m a photographer who can’t stand children. You want me to take pictures at your child’s birthday party — there will be games and clowns and other things I find annoying — and I decline.
No serious person would suggest that the law ought to penalize me for age discrimination — but why? Before answering, consider two more cases:
Case 2: I’m a photographer who disapproves of homosexuality; the mere thought makes me uncomfortable. You try to hire me for your lesbian wedding; I decline.
Case 3: I’m a photographer who disapproves of miscegenation; the mere thought makes me uncomfortable. You try to hire me for your interracial wedding; I decline.
Now, is the lesbian wedding case more like the birthday party case or the interracial wedding case?
