I have a problem with the inherent hypocrisy in this article. The author presents the issue of her sons "sliding to the right" as a problem in itself, rather than explaining why she thinks it is a problem.
If you, as a parent, see a shift in your child's belief system or political preferences as a problem, you need to do some introspection and be able to fully articulate why it's a problem other than "I don't like it."
