Be active in organizations, political or not, that express your own view of life. Pick a charity or two and set up autopay. Then you will have made a free choice that supports civil society and helps others to do good.
Some groups I have automatic donations to are local NPR and college radio stations, Northwest Second Harvest, and Northwest Abortion Access Fund. These reflect my values.
Giving money isn’t the only way to contribute, of course. I’ve been writing postcards to voters in the last few weeks, for example. In the past, I’ve helped run fan conventions and hosted a book club. Different folks have different interests and talents. But we all live in a society.
