This is such a bad faith argument. No one is being forced to write specific messages, but merely follow the law. The law that states that to legally do business then the business will not discriminate against certain classes of people — This is not unusual, there are tons of laws a business must follow to stay open.
Protected classes are narrowly defined. You may or may not have an issue with what those protected classes are, but that's a separate argument. The main argument is that businesses must follow the law to stay in business.
