The red states are not inusulated. In fact, they are becoming less insulated. However, the left is out of touch with the rest of the country, so much so, that they don't realize they are out of touch.
No, we're not. For the most part we're very well read and travelled (I've been to every continent except Antarctica and Africa). What the blue-staters don't understand is that we've taken a look at their globalist/utopian plans and have outright rejected them. It's not that we're ignorant; on the contrary, we understand their plans very well (again, because they love to talk about how wonderful they are)--we just don't want any part of it.
