In theory I agree with you but at the same time it seems incredibly naive to me to think laws that force homophobes to work with gay people against their will, are going to fix discrimination, to be honest that would even create additional problems imo. How do you even want to put that in practice? Force the photographer at gunpoint to take nice pictures on a gay wedding? i don think that would be practicable. Maybe fining the photographer if he is stupid enough to be honest about why he refuses a job? Well, from now on he will just say his schedule is full when a gay person calls. I just can imagine any realistic way this would work tbh.

Of course open and structural discrimination needs to be outlawed, like having signs that say “No blacks” or “No gays” but the issue of individual discrimination can not be solved by the law, it can only change through real social development towards a tolerant society, sorry USA but that is how it looks.
