the entirety of human culture has been making a steady shift toward the conservative for... oh since the last time the pope died? the last pope was very (relatively) liberal. what happened just 40 years ago in this country? huge liberal outpouring from all sides. then what happened? those hippies and their children grew up and got scared (of commies in the 70s especially) and 'found jesus'. not to mention the apathy of the youth (the expected source of levftist revolutionary thought) which prevents their influence on the government.
why did this happen? because liberalism (note. i use this in the new meaning which makes me cringe.) failed to give our parents the stability they thought they needed. it failed to solve all their problems all at once. so they made a huge shift to the right. where have we seen this before? the fall of the weimar republic and the rise of Nazi fascism. and yes i am calling our government fascist.
