Protests and ethics and capitalism and products and politics are more complicated than that. If collateral damage or somehow hurting anybody in "your" half of The Two Groups (which is a faulty premise to begin with) is ruled out, you're wiping out nearly all opinions and protest. Things just aren't that simple (though it's convenient to pretend they are when it lets us point a finger at the enemy out-group - look at their hypocrisy/in-fighting!)

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.
