Here's a provactive cartoon, Suicide of the West

I thought this cartoon was really disturbing when I first saw it.  The way Western Civilization cripples itself with political correctness, progressivism, socialism, and other liberal ideas expose America to fatal attacks.  I think that as Americans we have to acknowledge that even though we have a free society with freedom of speech, there are ideologies out there that if left unchecked can destroy that freedom.  The great American experiment can be destroyed by radical Islam, communism, socialism, fascism, liberal progressivism (which really is just a front for socialism), and Black Liberation philosophy (like what Rev. Wright is always preaching).
