I'm more concerned about parents letting their children access Twitter (even if it's only to follow Sesame Street characters) than Big Bird getting the jab.
That's the hilarious contradiction here. Most of these helicopter parents are fine with feeding their kids several thousands of calories every day and letting them play on the internet round the clock. If they actually cared about parenting, maybe they'd bother to do a little bit of it here and there. The reason they're so scared of a show like Sesame Street saying something they disagree with is because they rely on the media to raise their kids for them.
