The reason why we‘re winning is because people literally changed the course of history.
It is a spectrum imo, not black and white and the closer you are to the issue, the easier it is to solve.
Thats why many books propose the „circles of influence“ that split your world into things you control, things you influence and the weather (which you neither control nor really influence).
The first you should take the most serious, the second you should participate in, not loose sleep over (voting, lobbying, speaking up about problems), the last you should leave be since you cant change it.
The hard part is deciding which is which. Participating in political discourse definitely is important imo.
