I have to admit, I've only seen a few images of Barack Obama that weren't still photographs or caricatures, so maybe he has some hypnotic trick he does with his eyes or voice inflection that I'm unaware of. Other than that, I can't imagine why parents who consign their children to 13 years of government indoctrination would be up in arms over their appointment to see and hear the Glorious Leader.
What is the big fear? Will Obama make a statement that you cannot refute? Will he wow your kids with his superior ideas and logic? Will they immediately shuffle off to the limestone mines and start cutting obelisks?
Of course not. Just like every other night the kids will come home, you'll sit down to a nice family dinner where everybody relates the highlights of their day, and then, when the dishes are cleared, you'll sit down with them to help them with their homework. As the subject of Obama comes up, you will help them use the reason and logic tools you have already taught them to glean truth from propaganda, question authority, and make their own informed decisions.
