The fundamental premise of sci-fi is not spaceships and lasers - it's that children can learn from the mistakes of their parents.

My first duty to write a gripping yarn. Second is to convey credible characters who make you feel what they feel. Only third comes the idea.

Science has learned recently that contempt and indignation are addictive mental states. I mean physically and chemically addictive. Literally!
