“Does a poor upbringing make you more left wing?”
Any upbringing that leaves you more left wing is a poor upbringing.
It’s interesting that my local paper, the Albuquerque Journal, had a similar story on Friday as their Front Page lead. The headline: Lean to the Left? It May Be Mommy’s Fault. It stated “Researchers at the University of New Mexico think they know why aunt Bertha is an ACLU-card-carrying liberal while cousin Winthrop is a rifle-toting conservative. Blame it on their parents. A new paper in the journal Evolution and Human Behavior suggests that those who have experienced stresses in childhood – divorce, family violence, angry parents – are more likely to be liberal. Conservatives, meanwhile, are more likely to have had less stressful childhoods.
