Attention is limited, but also fragile. It comes from whatever people are passionate about, and shutting that down just makes people disengage, it doesn't get them fired up about something else -- least of all the thing that was important to whoever shut them down. So it's not a decision about "we have 10 attention, where do we put it," it's about "what generates more attention for us to use in the first place."

It's obviously selfish for people to disengage just because their feelings are hurt, but it's also just how people work whether we like it or not. I think it's important to acknowledge that, stoke whatever passions people have around this topic in general, and then encourage that passion to go further by redirecting it where it can do the most good.

Just policing which topics people get to feel passionate about, telling them to shut up and do better when they choose the wrong ones, doesn't really make anyone active for our preferred cause even if it's objectively more important. It does make us feel good to shout people down, though, by feeling like we're more aware than they are. I think it's very easy to convince ourselves that we're fighting the good fight when we're really just stoking our own ego.
