Like the gas stove shit (in the US). How simple was it for Fox News, etc., to get millions of people who had no opinion on gas stoves whatsoever minutes earlier, to suddenly be willing to die to preserve their right to own gas stoves against some faceless enemy who is, in their addled minds, coming to their home to forcibly take their stoves away?

You already pointed it out, you just aren't quite touching on the difference. These conservative morons (the ones being fed, not the ones preaching the message) are quite gullible and short-sighted. They operate on emotion, not reason.

The reason Left-leaning people aren't susceptible to such rhetoric is because they're more in control of their faculties. We may get worked up and emotional. We may fall victim to bad information. But we aren't driven entirely by the id.

ETA: Capitalism is built on lies. Tobacco industry lied for decades. Fossil fuel industry has lied for decades. Muskrat has lied for a long time, but I don't know how long (and don't care to check).
