Saying the same dumb thing over and over doesn't make it any more intelligent. I would describe this post as profoundly ignorant, given that the most painful interactions for this country (and planet) have come from conservatives, like Hitler and the religious conservatives who are slaughtering innocent people all over the world in the name of Islam.
I will agree, though, that where people think they have an accurate idea of where their pain originates, they make choices based upon that. But, what is painful to us is not always rationally determined. For instance, the American Christian conservatives, who fear the foreign, Islamic conservatives, deal with their pain by supporting politicians who espouse very conservative answers to their fears, like walls between countries, religious exclusions and carpet bombing their enemies with little regard for what either would mean in reality. Conservatives everywhere seem to be very comfortable reacting to their own subjective emotional states without caring too much about whether, in retrospect, their actions are wise or even accomplish the mitigation of what they fear. Attacking Iraq was a prime example of how conservative weakness and lack of fortitude has resulted in a foreign policy decision that has compounded the reason to fear.
I don't know what the worldwide laws are that stop humans from having "incest kids", whatever those are. What I do know is the vast majority of laws that currently protect children have been proposed and enacted by liberals. It is conservatives who have defended child labor and who currently seek to defund public education. Now, I realize that conservative rhetoric is full of hysteria about the unborn but that source of pain is nothing compared to what they impose upon the born, and their mothers, every day.
The question is not whether we are self interested, it's whether we have a clue about what's good for us in this environment where stupid ideas, like this thread, travel through cyberspace with as much velocity as intelligent ones. The thing about pain is, some times it's imagined and lashing out because of an imagined pain is to create unnecessary victims of our fantasy. Conservative dogma is notorious for being incendiary calls to action but, unfortunately, too often these calls to action are delivered by those with a very tenuous grasp of reality. There is no way to have invisible deities and the dogma of property rights be the foundation of humane, rational policy. Yet, there is a substantial percentage of the population, worldwide, who believe their own hypersensitivity is real pain and act accordingly.
Whether it's the pain of having women play an equal role in society or the pain of losing your religious exceptionalism, there is no doubt that conservatives are in pain. Their wailing and teeth gnashing are the well documented excuses for daily miscarriages of justice and the failures of human compassion that are represented by war and oppression. Yes, you're in pain. Why must you be so quick to make it universal, though?
