I'm not suggesting we shouldn't make people feel uncomfortable. I'm just suggesting that on the other end of that, at some point you can do more harm than good. And, in my opinion, that's plainly true. As an example (one I don't mean to derail with_ - Teacher strikes are happening all over and they are designed to cause discomfort. That's fine, I support that. But I'd guess that if teachers decided to make parents uncomfortable by holding their children hostage that it likely wouldn't help the cause. Now unlike my extreme example, determining where you cross the line from what's necessary to cause discomfort and where it is counter-productive probably isn't an easy one to determine. (And only then, it might be via hindsight) Nevertheless, it does exist and it can derail your movement even in the eyes of reasonable people if you're not aware of that. At the end of the day you want to cause enough discomfort to spur change of the kind you aim for. That's a difficult, delicate balance and because of that, I think it is possible to push too hard or in the wrong way and ultimately do more harm than good.
