Don't wear a mask. Social change is about many caring people coming together to support a worthy cause. Solidarity and visibility are key. The women's rights movement was not organized by cryptographers. Social change does not come from the shadows. Spend your time on simple basic things that support solidarity. Discord, web-pages, Whats App... use it all!

Model you tactics on successful campaigns and people. What does the ACLU use? How about Amnesty International?
