The issue is really quite simple:
If I own a 'convenience store' and do not sell beer or alcoholic beverages in any form because of my conscience views on the matter, that is my choice. A customer can not enter my store and claim that since I sell other forms of liquid refreshment, that I MUST provide them with an alcoholic beverage because it is the customers right to consume alcoholic beverages. The government does not have the right to compel me to provide goods and services that I do not wish to provide to the public. I have my rights and the consumer of alcohol has theirs. I do not wish to compel the drinker to stop drinking but do have a right not to provide the alcohol to him.
It is the same with the owner of the bakery. He did not wish to stop the gay people from living their chosen lifestyle but felt it was his right to not bake a gay themed wedding cake. LoveUniHateExams is pointing out one of the fundamental functions of a 'free market'. Buyers and sellers in the market place both have choices and are rewarded or punished by the market because of the choices that they make. Gay people should realize how lucky some of them are to live in a tolerant Western society that accords them the dignity and rights equal to that of their fellow citizens. Now gay people should realize that others have rights and free choice also and that even those who disagree with them should not be compelled to do their bidding.
