Is it though? Terrorism is the use of violence to achieve a political goal by creating fear in a population. The people who are targeting Tesla dealerships aren't directing their message to the general population, they're directing it to one Nazi in particular.
Exactly. They aren't even attempting to scare Tesla customers themselves. It's all about tarnishing Musk's image, sending a message, and damaging his cashcow.
Maybe I'm missing something if the "attacks" in question are water balloons or whatever. I assumed, possibly incorrectly, that something more severe was implied by that word. Like arson, or similar.
I mean, if someone was to burn a dealership down, that would be rather similar. I assumed a certain severity of attack, because that word implies a degree of violence to me. I may be wrong there. I don't think graffiti could ever be accurately described as an attack, for example.
