A conservative site which will remain nameless has a post today about progressive attitudes toward children. It is perhaps fair game to point out that because progressives as a group have fewer children, they might value children less. But I don't see how that applies to the liberals who actually do have children of their own. The post itself, and certainly the comments, included dire warnings about how bad liberals' children were going to turn out, and what bad parents they are.
Go back to the dugout, shortstop. Don't automatically conclude parenting values from political values which include some of the same words. More importantly, while parenting may be the largest factor in how children turn out, it may not be a majority factor and is certainly not overwhelming. Genetics (especially temperament), siblings, neighborhood, churches, friends, schools, books, media and chance all play their part as well.
