No, we don't always listen to stuff we agree with... Just off the top of my head I can argue any right winged position just as well as anyone on the right can... How can that be if I'm not paying one hell of a lot of attention to folks with whom I completely disagree...
Speak for yourself, Ake, but most of my progressive friends are like me... We want to know what the enemy is up to... BTW, I doubt seriously if too many folk on the right can argue our positions...
