Haiku of frustration

The pain in my ass.....
Why do I talk to these dense
Libertarians?

Seriously. I know it's good to get out and encounter different views- in some cases so as to refine your own views, in some cases in the interest of "know thine enemy", in some cases just for the sake of getting out for human contact. But, really, now. I have to wonder why I do this to myself, this trying to engage in reasoned argument or debate with some people is truly futile. Possibly they work for the aspirin company and are paid a hefty wage as Headache Farmers.
