Extremely condescending, often when he has little to no height from which to condescend from. Sure, you have similarly revolting takes from other right-wingers and socons, but at least they treat people they disagree with with a modicum of respect.
The condescension also usually takes the form of basic econ-101 rules of thumb (often applied in completely incoherent ways, such as the fact that he apparently thinks rent-seeking behavior shows a lack of profit motive), worded as if they're nuggets of divinely revealed dogma handed down to us for our edification. It's a shame Atlas hasn't used the "sage" meme for a while, because it so perfectly captures what makes his posting style so obnoxious.
