There must be 50 ways: Participating in democracy #46: Build a pro-democracy coalition

Right now we are reeling from the onslaught of Trump's actions. To me, the key is exactly what you envision, getting involved, no matter how few hours we might have, and, whatever we are involved in, we are communicating our dissatisfaction with the harm that Trump is doing. That is step one, to me. 

Step two is getting the group we work with to declare that, as a group. 

Step three is to look for other groups to ally with. 

Step four is for the coalition to declare its opposition. When we have a "group of groups" we have power. We can start to show that power to ourselves and others and make it easier to get change. 

The ultimate step is to simply have such a huge coalition that we can credibly threaten a general strike. It is often helpful to simply do such a thing for a short time, just to prove the concept. If, for instance, the coalition was big enough and prepared enough to go on strike for a symbolic half day, that might show enough power to get Trump to start negotiating. A longer general strike would need serious commitment and preparation.
