Can I just say that? I am not afraid for my kids to listen to a president address the nation's students. I'm excited that our president is taking time to speak to the importance of an education and perhaps light the fire of motivation in some children who don't have a 'cheerleader' at home to do that for them.
And even if this was a president whose policies I disagreed with, I'd still remain unafraid for my kids to hear what he/she had to say. I'd urge them to listen just as intently. I'd remind them to respect the office and the person. I'd want them to know that it's okay to hear 'other' points of view.
I'd teach them what I disagreed with concerning this or that policy/statement and why. I'd also teach them that respectful discourse requires two sides listening to each other and sharing differing viewpoints. I'd teach them that that's how we learn (and sometimes realize we don't know everything).
Listening to a presidential speech is a teachable moment, regardless of what 'side' you're on.
