    Libertarianism and authoritarianism are opposite ends of the same spectrum. If two hypothetical societies are heavily authoritarian and equally so, then they are both authoritarian. Libertarianism emphasizes personal autonomy and individual freedom. It is by definition non-authoritarian. Libertarian concepts extend from the left to the right.

    I don’t understand why you think that is a contradiction. You both agree there’s a spectrum between the two. Technically, if you’re not 100% authoritarian you have a greater-than-zero alignment with libertarianism.

    Now, if you’re trying to say landing somewhere in the middle of the spectrum means you’re neither, then I tend to agree with you (labels suck). However, I’d take it a step further and say that nobody is going to be the 100% perfect embodiment of either end of the spectrum, and therefore, no true authoritarian or libertarian exists. I think, to say either one of you is wrong is just arguing semantics.
















  • From your source:

    {The upper flow is faster and from Bernoulli’s equation the pressure is lower. The difference in pressure across the airfoil produces the lift.} As we have seen in Experiment #1, this part of the theory is correct.

    Sure, it might be more complicated and there are other forces at play. Also, top and bottom air molecules may not reach the backside of an airfoil at the exact same time, but that doesn’t diminish the effects of this pressure differential on lifting force.


  • That lift explanation is innacurate/incomplete. While there may be some equal and opposite forces depending on the angle of attack, the primary reason for lift is due to Bernoulli’s Principle. Airfoils have a rounded upper surface with a longer path for air to take, relative to the underside. This requires air to move at a higher velocity over the top, and since A1 x V1 x P1 = A2 x V2 x P2, pressure over the airfoil decreases. It is this pressure differential that creates lift.

    In regards to aircraft, Newton’s third law of motion applies to thrust from a propeller or jet engine.
