Mass action includes days with no buying, general strikes, street marches, boycotts, vacationing outside US, conserving cash including converting assets into money markets / CDs, signs, memes, posts, jamming town halls, jamming phone lines, civil disobedience, ....
1) Be careful in crowds. Be safe, exercise situational awareness, scope out exit routes (streets) in case something ugly goes down. Be strong though.
2) I can't urge any one person to break laws, including civil disobedience but I celebrate the latter.
3) Do you really need a couple of $4 lattes a day? How about a hot thermos of coffee brewed at home for under a dollar. How about bringing sandwiches to work. See how long you can go in a week or a month before you give yourself a treat like a meal out. Start thinking this way now. The skills will help for the long haul.
4) Reuse, re-purpose, repair. Get used to it now, it will help for the long haul. Darn socks if that's what it takes. Fix the car and live with it instead of splurging on a new (or new to you) car.
5) Find ways to slow down goobermint (conservative version of government, aka the government maga always feared but doesn't realize has already arrived), like with time-consuming requests. Muck-Vance-Thiel want disfunctional government? Show it to them and the magas. Chock government vehicle wheels so they have to get out to make the car go.
6) Boycott red state products, red hat favourites, red states. Vacation in California or New York or Canada (best!). Don't go to red state team games. Don't drink Kentucky bourbon.
With more thought I could go on, but this is long enough already.
