It's one thing to hold a boycott, but this is something else entirely. Especially when you're targeting (including doxing) people because of what car they drive.
I don't condone vandalising random Teslas and I've had many arguments with anarchist activists over it. They are cars owned by innocent people who just decided to buy a car without intending their purchase being some high flying declaration of political allegiance. What brand/type of car you drive may be a declaration of what political tribe you belong to in the US but over here in Europe it is simply a function of what car you liked that is reliable, affordable and best suits your needs. I know this is an alien concept to politically polarised Americans but that really is how we pick our cars over here. Furthermore, it is also unacceptable for MAGA pundits to conflate arsonists with people who simply saw Elon give his Hitler salute and instantly decided they would consider buying any brand of electric vehicle other than Tesla. There is no law against boycotting, even in the USA, although that will doubtless change.
