"Why isn't anyone doing the obviously much better thing?" - someone not doing that thing

I'm not American. If I went there to lead the revolution I would end up in El Salvador.

I did, however, got involved in politics in two countries I live in and did a lot of campaigning for them, so I've actually done the deed as far as I could rather than merely talk about it, and did so further than just demonstrations.

Demonstrations are nice as a way for people to know that they're far from alone in their concerns, but they're worthless if not leveraged into helping make or grow grassroots organization to change the actual underlying problems that results in somebody like Trump getting elected again and again (and I'm pretty sure that if that doesn't change, when Trump is out somebody else like him or worse will eventually get elected).

The Georgy Floyd demonstrations are a great example of what happens if demonstrations aren't leveraged to grow civic-society movements for change: you get some vague promises from politicians and then nothing actually changes.

I just feel that people here are treating these demonstrations as some kind on getting near the finish line when they're at best (and hopefully) a beginning, and not even a beginning of the end but and beginning of the beginning, and they should be treated as opportunities to get the ball rolling on things that can actually snowball into real change.

If all you do after a demonstration is pat yourself on the back for having "done something" whilst you don't even have some contacts for groups of people you're thinking of joining for further actions, you've just done exactly what the actual powers that control the country wanted you to do: defused your anger whilst not starting the ball rolling on real change.
