A very very interesting article expressing thought on how dedicated "stay-at-home to raise their own kids moms" are a threat to the progressive's plans.
These moms are a counterweight to the state, and are subverting the state's control with their school agendas, with their steady loving influences. If you don't reinforce the state's message you must be challenged.
There's much more here than I'm attempting to summarize, so I think you should read this well written article yourself.
