Examples of simple, non-aggressive things that anyone can do:

• Get healthy. You will need physical stamina.
• Make a space in your home for short or long term guests. There will be refugees.
• Plant a garden. There will be shortages.
• Record, report resist. Use your phone to record fascist activites. The linked site is one way to make sure those videos are publicly available.
• Build networks with neighbors and friends, online and off. We will need to support each other.
• Learn how to prepare rations, even if it's just hard tack. Armies fight on their stomachs.
