On The Glenn Show, Glenn asks Harold whether social science can make sense of the massacre in Newtown. Harold is disturbed by the way that gun manufacturers advertise their wares and by the “fundamental unreasonableness” of many gun enthusiasts. They also debunk some pernicious myths about guns. Looking back at the election, Harold tries to cure Glenn of his political cynicism. Glenn expresses skepticism about the triumphal narrative of immigration reform. They close with a personal discussion of the generational divide over issues like same-sex marriage.
