Years ago I used to train folks to make those phone calls, write those letters, visit those elected officials when they were at home etc....

And for folks who have never done this it can be daunting....generally the pros make out a little script...for phone calls etc...NETWORK does....

My recent post Trump experience strongly suggests that it's the 6000 Indivisible groups that are training their new members in these matters...it's not the Church.
The Church just talks about it a bit...craven episcopal behviour for the most part, officially... concern without much practical help on the other side.

In my neighborhood there are at least 6 Resistence groups...they meet regularly, at a Methodist church, the library, people's homes AND in meetings with electeds.

They have been trained by the Flippable folks, are reached regularly on FB with internal networks and are definitely active...I just wrote a whole mess of letters at our local library with them, made phone calls and posted data.
