I don’t care for the caveat of religious reasons, if it is my business, my risk, my investment, my blood, sweat, and tears, I should have the right to refuse to do business with anybody for any reason I so choose
If I were a photographer of a wedding cake baker, I think I would do it, but do a crappy job, maybe even crappy enough to ruin the whole event....that would be especially easy for the photographer, he could just say he had equipment trouble...”oh man, I am so sorry, I dont know what what happened, my camera must be broken, those pictures all turned out dark and blurry....here I would be happy to give you your money back....
