"Wrong. Separate but equal was about race, not choice."
Would you like to re-read what I wrote again?  How about I break the single sentence down into easier to chew spoon-fulls?
"That concept," meaning businesses being free to "do what they want" like discriminate against blacks.
That concept "expired" and is a dead concept as federal law prohibits it.  The same kind of law that states use to protect more than racial discrimination that prevent business owners to "act any way they want at their own business."

Do you get the point now?  Legal precedent is quite set and has killed any belief that business owners are free to discriminate based upon race, ethnicity, nationality, and under Anchorage ordinance sexual orientation.
