Might effect new buyers decisions I guess, but since about 99% of Tesla's were sold to green, left-leaning buyers, before the Elon hate-fest, I am not sure how targeting that group of people for your hatred is helping any "cause".
That is not to say the opposite - that I think all anti-Tesla hatred/actions are justified. I'm just refuting your opinion specifically.
I have a lot of thoughts that run in both directions on topics like this, including this one. However, this specific case is especially far gone, in terms of drawing lines between "understandable" and "unreasonable" on any given anti-Tesla action/opinion, simply because of the fact that he and some of his supporters invoke Nazism. If it wasn't for that, I could more confidently say something like, "No, that one is over the line" for any given anti-Tesla thing. But I can't.
