I have not. Are these things you advocate?
I have picked up garbage around my neighborhood. Kept my sidewalk clean and tidy. Helped neighbors w basic tasks.
Does this count?
You're not going to get far talking to political fanatics. And like you said, they very likely do not have their own houses in order.
Everybody should submit FOIAs. If that makes me an advocate for public records, then sure, I'm an advocate.
And of course those things count, but it's arguably only focused on your immediate surroundings. I've done some pretty significant cleanup of parks in my area. It's very rewarding.
Are you interested in being less antagonistic about basic civics?
