The argument that prohibiting me from discriminating at the lunch counter that I own is flawed.
Libertarians say that the prohibition limits my freedom.
True. It does. But you are NOT free to punch someone in the nose just because you feel like it.
Freedom implies responsibility. Your "rights" end where my nose begins.
The freedom of the black guy who wants to eat lunch is hurt far worse by allowing such discrimination
than yours is by prohibiting it.
