All very good questions. To answer them, I will address what I call the de-facto religion of that state.
I always tell people that there are two things that make up this de-facto religion of the state: neoclassical synthesis (economics) and critical theory (sociology). Anyone deviating from these two “religions” is going to be an enemy of the state. Deviating from one is bad enough, but if you deviate from both then you’re going to be demonized even more. Libertarians in the Austrian tradition, whether left or right, all unanimously agree on the bankruptcy of neoclassical synthesis. From the micro sphere of neoclassical economics to the macro Keynesian models, there is little discrepancy here between the varying camps of Austrians. However, the same is not true for critical theory, as I’ve already indicated.
Left-Libertarians (LL) recognize how academia, the media, etc, “brainwash” the public into accepting neoclassical synthesis, but they cannot see how these same forces “brainwash” them by instilling CT. Quite simply, LL cannot see how the state and the so-called superstructure has influenced their thinking. CT is accepted by some LL, but it is slightly different than the Marxist version. The Marxist version of CT is a bit more ruthless and It essentially states that all white heterosexual men are responsible for everything bad in the world, and that everyone else is victim of their oppression. I don’t think that many LL actually believe in this, but there are traces of similar thinking.
For example, many LL share the “all non-white males are victims of oppression” view. Admittedly, there is some truth to this, but this fact often prevents LL from making value based judgements in the field of sociology (probably because they fear being called a racist, sexist, etc). If it is pointed out that blacks cause crime at a higher rate than other races, then the LL often comes to their defense. If it is pointed out that women have a lower marginal productivity in the workplace than men (on average), then the LL comes to their defense. These are just some examples, and not all LL do it to the same degree, but such lines of thinking represent an implicitly inherent egalitarian way of thinking (social socialism), which they are unaware of. As I’ve already indicated, LL do it because they carry the value-free methodology of economics and praxeology and extrapolate this same thing over to sociology.
I do think that many libertarians think this is a bunch of nonsense, but are afraid to speak out against it. In todays world, you’re considered to be a “racist” when you argue against universal health care; you’re more of a “racist” when you argue against affirmative action in colleges and at the workplace; you’re even more of a “racist” when you suggest that blacks and Latinos commit more crime than whites. While the Marxist version certainly does make value-judgements, the LL version does not; it’s more of a white-guilt installation by academia and the media, and libertarians of all stripes have a fear of speaking the obvious because they might be called racist, sexist, or what ever. Either that, or they are just beaten into submission by the state, academia, and the media.
The reason that CT is sometimes harmful is because this line of thought can serve to increase the power of the state. For example, there was a rallying cry from LL regarding the Don’t Ask Don’t Tell legislation that prevented gays from openly serving in the military. In reality, repealing this legislation just empowers the state further. It would be better if gays were banned from the military entirely. It would be better if women were banned from the military entirely. It would be even better if men were banned too. See where I’m going? Why empower the state further? I also think that LL, under the spell of CT, are in error when they argue for open borders because they don’t understand the sociological implications of such a policy (I don’t want to address open borders here because I’ve already done so in other threads).
I don’t think that it’s unjust for the government to discriminate in certain instances. Rothbard makes this point in that article that I linked to “Big Government Libertarians.” Hoppe makes it in “Democracy.” Point being is that, even some Austrians, can implicitly empower the state. CT helps LL do this without them even knowing it.
