Of course I can see why your opinion isn’t very popular — most of us are instilled with the belief that truth and honesty are virtues from a very early age — but I can also definitely see the pragmatism of it. Why expect truth from a system that rewards untruth? The basis for your thinking — that action is much more important than empty campaign rhetoric — is persuasive.
But if no one values truth in the political arena — politicians and voters alike — then I wonder how we will decide who can or will take the actions necessary to improve society. If all political discourse is a priori bullshit and everyone knows it, how do we choose among various bullshit artists?
I’m not implying that you should have a solution to this problem — which is becoming less theoretical and more realistic everyday — but it’s a problem nonetheless.
