Eugene Volokh writes about a hypothetical scenario involving a mixed-race couple in the photography incident:
The desire to prevent race discrimination should no more dissolve your right to be free from being compelled to speak (here, to create an artistic work) than it should dissolve the right to express bigoted views, to choose members of a racist political organization, or to select ministers (or church members) based on any criteria a church pleases. And if that means that writers and photographers can’t be legally barred from choosing their subjects based on race, that’s just an implication of the basic First Amendment principle of the speaker’s right to choose what to say.
There should be nothing particularly daring about this position.
Needless to say, I agree. And my position will remain the same if I am discriminated against by someone in the US because I am an Indian.
