Sean Hannity recently interviewed several High School seniors from New York, and I was astonished how dumb they were- they were ignorant on homosexuality, abortion, and especially the war on Iraq. They're support for homosexuality was "As long as you love somebody, you can marry them", for abortion "Her Body, her choice", and for Iraq were a series of idiotic statements.
Brambila, maybe that's New York City, but most young people (at least in my school in a fairly centrist, right-leaning county) I've seen are pro-life (and I also realize that's not a scientific study).
But even so, those quotes you posted with the exception of any Iraq statements that were made (I'm sure those were pretty dumb), to me it shows an open mind, and the abortion statement simply reflects their views on a touchy subject that are difficult to change. Not everyone thinks about abortion the same way you do.
And I'd like to see Hannity go down to Mississippi and interview some high school students there, see what they have to say -- just to balance out the ones from New York.
