Has anybody heard of the whole #DisruptJ20 thing? It seems to be an umbrella movement for anarchist, feminist, and black power movements to march under together for the sake of violently stopping the inauguration. Planned Parenthood is on board with things but appearing to expect only nonviolence. They're in for a time. The organizers are training people for violence and street first aid. They plan on blocking traffic and coming in waves to distract and attack. Their mantra is "no peaceful transition." They appear to have about 200,000 people so far and are instructing people in other states on how to wreck havoc. Also, they have told people in other countries to attack embasies, borders, or other symbols of "colonial power." These people are well organized and violent. Stay safe.
If you want to go down the research rabbit hole for yourself you can visit their website. You can find some groups affiliated with them and through those groups find even more. Remember: These people are not peaceful. Some of those groups I've found include: wakeATL, Anti-German CrimethInc. Cell, NYC Anarchist Book Fair, Pitt Students For a Democratic Society, UNControllables, Antifa Seven Hills (and many other antifa organizations), Asheville Anti-Raceism, International Anarchist Federations, Chicago Anarchist Black Cross, and of fucking course Black Lives Matter.
