I think that was a rare case though. Two STOOPID things happened there.
The photographer (like most business owners in fields such as the photographer) can still discriminate if they like, they just have to be more creative about it.
Just say no. Too busy, booked, etc.., or refer her to another photographer - You don't even HAVE to give a reason. She did though, and quite vocally.
Second, the major unfortunate problem the photographer faced was: She said it to someone whose job it was to enforce discrimination laws.
The lesbian (radical, in my view) worked for the NM version of the EEOC. It was what she made her living doing. Yikes.
Bad Bad mistake. It was like telling the Liquor Commissioner you own a bar and serve booze to minors, or telling a cop you speed every day around a certain stretch of road (maybe not great analogies, but it's a slow-firing neuron day. lol) Not wise.
The photographer was nabbed in a very unfortunate situation, but it was state law.
My personal views are that art fields, including photography and such, are not something that should be open to Civil Rights Laws.
It is quite different than a general store, restaurant or hotel.
