So, there’s this website and downloadable pdf called Invisible: A Practical Guide for Resisting the Trump Agenda. It’s where “former congressional staffers reveal best practices for making Congress listen”
It’s pretty dandy y’all should check it out
Also take a copy of The Activists’ Handbook by Aidan Ricketts which is an incredible book and a great stater for anyone who is brand new to practical activism and needs a helping hand on how to start in a safe, responsible and practical way
