My sense looking at the last few years is that resistance is more like a habit than a muscle. It's not that your capability to resist gets stronger each time, it's that it becomes a reflex.
The upside to having the reflex is that you stand up against unfairness more often. The downside is that it becomes a simple response to a stimulus rather than a conscious choice, which means you end up constantly caught up in the cause du jour without ever stopping to think about whether this particular case warrants your limited time or even whether it's actually a case of true unfairness.
