Both the Left and the Right, in general, share a mindset of discrediting and smearing opponents.
If one dares challenge the orthodoxy of the Left, you are a racist and a fascist. If you have the audacity to challenge the doctrines of the Right, you are a terrorist and a communist. The terms differ, but the intellectual dishonesty is similar.
Both ideologies have destroyed America. The Left wants to turn us into a "less blonde Sweden," while the Right would convert us to a giant parking lot with the governmental viability of Somalia.
