gpm's point is that it's a collective action issue. And even if one individual can't fix is, we can with a movement. And we SHOULD care about things like this. We're fairly familiar with these: big problem, only solved if enough people do a thing. But in general, almost all collective action problems we face are ones where either:

a. every incremental actor improves the overall picture with their individual choice (however small, even if it takes a threshold to be "solved": think, recycling, vaccines) b. every individual actor actor's choice has no _direct_ impact until some threshold is met (maybe voting?)

THIS situation, however is very different: every individual choice for blue makes things WORSE up until the threshold is met. And not just a little, but a LOT worse. That's not normal collective action territory, so we shouldn't be assuming the same kind of reasoning. The stakes of missing the threshold are not "aw shucks" or "keep trying, there's more chances later!" The stakes of missing the threshold are "everyone who cares about the threshold is dead."

I can't think of anything IRL that falls into this category?
