I feel like you’re missing the point a bit. Living by values you hold dear is not losing, winning or even necessarily a cause. If your values happen to align with a cause, then supporting it in a way you can is at least somewhat fulfilling.
Now, there are definitely people who join a cause for tangential reasons. For example because they are a vehicle to what they want, such as someone who wants to build and use explosives can just as easily become a fundamentalist, anarchist or fascist. (And history has examples of these sordid folks.) They barely care about any of the causes and will drift wherever they can live by their own values, even if it’s about blowing shit up.
There’s also the ADHD DLC variant of: I put it down wherever I suddenly completely context swapped to something that needed my hands free and have no idea what I was previously doing, what I had in my hands and where it might now be.
