This is an attempt at a communications guide. I’ll edit it as we go along; pop suggestions in the comments!
People are often angry about politics. To give them something new, we must instead inspire excitement and awe. If we talk positively about an amazing future, we give people something to fight for. So, always talk about how we can build a better future; don’t lead with how the old parties are getting it wrong.
For instance, if making a point on surveillance legislation, maybe lead on the story of a future where people are empowered but in control of their own information; then point out how our current approach is undermining that.
Wherever possible use simple words and short sentences. It’s not always possible, but it’s a good aim. Use simplewriter and Hemingway to create simple understandable text.
Remember, people don’t read everything to get to your point. Have a TL;DR at the start; make content skimmable, and remember the Inverted Pyramid for writing.

What’s the short shareable message from what your writing? Pull it out clearly.
