Our country was founded on the exact opposite premise.
Pure speculation.
That is because your speech is or has to the potential to inflict harm upon another. Refusing to service a person does not such thing.
You do realize our founding fathers were a bunch of racist bastards, right? Remember the three-fifths comprise?
Reminds me of Tosh's stand up:
Daniel Tosh on the Founding Fathers and Equality of the Sexes
This is were you are inserting your own moral outlook and view of a perfect society unto others.
If Ras had a men's only establishment, would that harm the general public?
If Gibbs opened up his Marxist pringles restaurant (only other pringle lovin' Marxists are welcome), would that harm society?
If GS opened up a tinfoil only lodge, would that harm the public?
There is no harm done to the general public when a private business is allowed to operate as it so desires, so long as it does not violate another's life, liberty, or property.
Living with and allowing others the freedom to practice whatever they believe is the height of coexistence. Artificially enforcing rules upon others, limiting their freedom is hardly what I would call true coexistence.
Oh man. So laws ought to be based upon morality? Just take a moment and think about the implications of such a notion.
Let's for a moment concede that legality is inextricably tied to morality. It becomes a chicken or the egg argument. Are laws just because they are moral or are morals just because they are law (being the will of the majority)? Such an argument is very similar to the uber famous
Euthyphro. In
Euthyphro, Socrates asks Euthyphro whether an action is pious because the Gods like it or do the Gods like such an action because it is pious?
Law and morals are not inextricably linked as many would like to believe. This is where the fundamental Christians who claim our legal system is based on Biblical commands/morality go awry. There are countless things a majority of Americans find immoral or taboo that are perfectly legal.
To address your example, it is not against the law to kill a man because it is immoral. It is against the law to kill a man because it violates another man's life, liberty, or property; obviously "life" out of the three. One would not want murder to be legal in any social contract due to their own self-interest to stay alive.
