Thanks to voters like you for Brexit then I guess.
Sure we're all stupid, but I'm putting my money and energy into what I want to make better, rather than worse. Sometimes that drive to do better comes from spite.
I vote and tell others to online here and in real life, I attend city council meetings for the stuff I care about (transit), I go out and meet the poor and suffering where they are and donate to my local food bank. When I boycot something I stick to it. When a platform turns too shitty I find ways to get away from it (Lemmy), or at least get it to arms length (Matrix/Beeper).
Issue is, there's only so many things that I can be not complacent about. The Gaza war is terrible and I talk about it often, yet it's just a situation I can't see a way I can convince the US to hold Israel to account no matter what I do. Rents, affordability, climate, there's stuff I care about but when I am back from my full time job there's just no more room to think about how the world is fucked 10 ways from Sunday, and my mental health is better for not focusing on things I can't fix.
To boil it down for you:
I can do a lot, but I can't do everything. I'm reserving what I can do to stuff where I can make the largest impact.
