What is the author's opinion regarding business transactions with people holding personal ideologies that may differ from the business person's beliefs?
Unless said baker is very stupid and is looking to be put out of business then the baker would of course decorate a silly cake with the inscription, "The Catholic Church is the One, True Church of Christ on Earth," take the person's money, and then cry themselves all the way to the bank. Every minute of every day of every year business people do business with people whose personal ideologies may offend them if only they knew their innermost thoughts. It is the selective moralizing evident in these particular cases that is at issue, and everyone knows it.
