The American people deserve truthfulness, not more political campaigning. The American people deserve a responsible government that seeks to address their needs, not more ideological dogma.
Spiritually, we're all on a path. I haven't declared of defined myself because as soon as you declare yourself you're identifying with a certain dogma.
So the idea that there is nothing essential, in the sense that there are no human universals, is dogma. Ask most anyone who is going to be shot at dawn.
Christianity, with or without its whole apparatus of dogma, will endure in its essence for thousands of years after us; there will always be spiritually-minded people who will be ennobled by it, and some made great.
