I disagree. I think when people encounter extremist speech, they have an initial strong reaction, but then the idea sticks in their head and becomes normalised. Over time, that reaction subsides. The overton window shifts. Those Nazis in the whitehouse have been shifting the overton window right for more than a decade. At first, the public had an initial strong reaction. But then their fascist ideas stuck in their heads and became normalised. And now look where we are! The mainstream left has been pushing moderates like Joe Biden, who don't provoke any initial strong reactions, but they don't inspire people either. Their ideas don't stick in people's heads. We need more extremists in left wing politics, and we need more extreme leftist messaging.

COWS DON’T WANT TO DIE

We need to keep yelling it until it becomes normalised, and then people will take it seriously. Most people are conformists and will react to anything they haven't heard before by shutting down. It's actually kind of useful, evolutionarily, to be a little bit of a conformist, because it helps you fit in and avoid in-group conflict. It lets people work together more easily. But we also need radicals who are willing to shift the normal in a positive direction. And once radical ideas become normalised, only then do most people take the ideas seriously and evaluate the evidence.

Also I did go and research the claim, and it's true. Temple Grandin designed modern slaughterhouses with semicircular arcs for the cows to walk down, which match their natural herding behaviour. The serpentine passages minimise visual distractions which spook cows, and then lead to a ramp which takes them to the stunning area. The ramp keeps them from being able to see what's going on until they're stunned. And then a human knocks them unconscious with a bolt to the brain and slits their throat.
