Hi everyone! One *extremely meaningful* thing you can do to fight back is to join library boards. Usually this is an appointed position, not elected. The time commitment for most public library board members is 1-2 hours monthly.
I'm a former library director. Ask me anything.
And to tag on to this: For the People is a great group looking to help get left-wing people involved with their local library via joining boards or other meaningful supports! www.librariesforthepeople.org (full disclosure, I volunteer w/them)
