For those interested in 2A activism or becoming organizers, I recommend taking these 4 free online training sessions from the Leadership Institute on running campaigns.  It's open to anyone.  It's focused on political election campaigns, but the same elements work for 2A activism.  Engaging with people, effective arguments, building the base, communications, fundraising, etc.

I've met people from the Leadership Institute and it is a legit organization that believes in constitutional rights and less regulations by the government.  They used to have a training center in Honolulu but are now online.  They have other classes, some free some paid.
