@kev responding specifically to your clarification: I disagree completely.
Collective action is essential to effecting change. We absolutely **must** say "you shouldn't buy a Tesla because Musk is a dick" and broadcast that to our social circles if we want to actually effect change in Musk's behavior (impossible as that might seem).
We shouldn't browbeat random strangers about it, that's just being a dick yourself, but I absolutely will tell anyone I actually know who owns a Tesla what I think it says if they ever purchase another one.
@tim It's a very fine line, and crossing to the wrong side of it can actually hurt your cause. Unfortunately (and especially on social media) what can be meant to be helpful can come across as "reply guy" and dismissed out of hand. Extreme care needs to be taken, and often it's not.
