Many municipal and state laws do, but I think from a Federal standpoint, it is perfectly legal to deny public accommodation to homosexuals.
Not sure if that is correct, but just as Trey Gowdy tells us that the power to subpoena is only as effective as the accompanying power (or lack thereof) to force compliance, what the laws say are no longer an indication of the reality. With military being told that they cannot expect promotions if they don't "exhibit a real tolerance for the various sexual lifestyles", it is only a mater of time before they are protected fully (they will be right and everyone who disagrees will be wrong).
Who knows, when Obama relates one to the other, he may be signalling that what I just said is being prepped to go into affect.
