This demands faith in a certain human ideal -- high above the corruptible idiocy in display in politics -- the basis which produced those indefectible experiences, feelings and ideas most people had a chance of experiencing, or at least had a small glimpse. No matter what happens, one can't lose faith or abandon this defense of the basic human ideal (if only your own humanity) in favor of anything else, or nothing else. It's not about optimism (although optimism can be an important tool in this persistence), it's about maintaining all that is good in the universe (again at least in your own life and loved ones, if it comes to that).
We may go (indeed we will go eventually), but let us go living, and fighting, for what's worth living and fighting for; hollow ones (worshippers of gods or capitals, nihilists and ignoramus) be damned.
Be safe, friend. And Don't you dare go hollow :)
