The physics and math communities get plenty agitated at ludicrous pop-sci and Hollywood depictions, cranks who think they are oppressed geniuses with important answers, etc. Approach just about anyone with arrogance and contempt for the methods and body of knowledge they spend their life on, and they won’t be happy about it.

Difference between annoyed/amused/slight despondency and narcissistic rage.

It's kinda of like this, a mechanical engineer doesn't feel threatened by some guy selling a magnetic doohickey you put in series with your cars fuel line to increase MPG. He just thinks it's stupid. He's not mad though.

Economists get angry.

And some physicians get mad at homeopaths. So what?

> Go ahead poke at Milton Friedman and watch them get really hot under the collar.

Who is them? Do you think economics hasn't made any progress sice the 1970s and everyone is a paleomonetarist?

Oh I think progress has been made, retrograde progress. Economists as less competent now than they were back then.

It is exceptionally difficult to prove economic theories because experiments cannot be repeated. The variables are always changing, and there is far from complete control over them.

Microeconomists and behavioural economists do indeed conduct repeatable experiments. This is more difficult for macroeconomists, of course, but the same is true for many sciences, such as theoretical physics, climate science or much of biology.
