Tao: "Healthy interactions between two parties require the free consent of both, and forcing one to associate with another without his consent is more fundamentally lacking in respect for free association IMO than allowing one to decline this association."
I am conflicted as to the optimal path of refutation here. In a society/societies, interaction is paramount. "Healthy" is a highly subjective adjective, and what is healthy for those in the transaction participating and what is healthy for society-at-large by simply having the transaction occur--sickly, resentful, uncivil, pick your perjorative--is not, IMO, easily divided. If supermarkets or corner stores refuse service based on bigotry, this an unhealty transaction; if they supply a crappy-but-ultimately-acceptable-because-you-got-little-choice service, the transaction is not healthy between the participants nor society at large. Arguing that that the Jim Crow laws are OK because they protect one segment of society from providing a service is, IMO, a vile and quickly-refutable argument.
When the service offered is often a human need, such as hydration, nutrition ("we don't sell that to people like you, only people like me/them") it produces an unhealthy society/Zeitgeist thay disserves and disgraces the society, its individuals, and historically has led to violent infighting within Every Empire.
Thus, IMO it's a decidely unhealthy Libertarian "principle" that asks a good deal of The Empire of the Republic (or any nation, or for that matter an Anarchist commune) to accept wanton bigotry as An Ideal they can use as a crutch.
The legality of burning an American flag on U.S. soil is consecrated (Texas v Johnson 1989) but not of a burning cross (not due to religious reasons, but rather the historical context) are crucial SCOTUS decisions. At the time, I was heartened by the first decision, disheartened by the second, but came around once I understood the historical context of the second decision (one of the last that that idiot Thomas actually spoke aloud during oral arguments).
Yeah I was blindsided by the Anarchism paradigm, which certainly should have been included in my second paragraph. Phiman252 deserves accolades for bringing it into the discussion.
Tao stated "[A} business owner that disallows a certain group from doing business with it automatically loses the business of that group, something that is very much against his interests."
Again, I will refer you to Black Like Me, wherein The Tyranny of the Majority rewards the discrimination of a "class of people" (for lack of a better term) by refusing to provide the basic services they require as the others in the Tyrannic Majority--they are provided such services, leading them to view themselves as better, more priviledged, and ultimately (in the Jim Crow era) better citizens. This is a direct refutation to the quotation I've taken, and I do believe I've taken it in context and thus fairly.
As the most obnoxious NYC Jews do, they refer to themselves as "chosen" and will not deign to touch your skin as it is the antonym of Kosher [I was taught by an observent Jew what the direct antonym of kosher was, labelled my can-opener as such to keep the peace in office, but sadly my recall fails me when I next need it most]).
I intended to delay introducing another aspect that deserves robust discussion in this forum, but it seems that at this point in the discussion the plain question must be presented:
Is Liberty (as conceived by self-identified Libertarians) and
Social (or Personal) Injustice [unremedied, that is, Denied or Perpetuated]
compatible?
Without an overriding interest in Liberty, my first best answer is No.
As to the free-market weeding out corruption/nepotism/good-ol'-boys network, I am simply unimpressed by your illustration, and will cite the historical record only if you press the point.
