can you give a specific definition of what constitutes psychological warfare or not, that you can present to a jury and get a reasonable judgement from reasonable people. Let's make it a standard that is specific enough that a jury would be less likely to be swayed, for example, by the color of the skin of the defendant or plaintiff.

I don't have much hope for us finding a legal definition of what psychological strings you are and aren't allowed to tug on and how hard. War crimes set a line for tugging until they break. It's a lot easier to define "way too much" than "too much".

This discourages me from wanting to go into long thought train about what I would like to outlaw. What I feel more confident about is adding lots of friction to the system.

A specific definition of what is psychological warfare is required only if you're trying to enforce it by law.
