So, you're an evolutionary psychologist. How do Bronze Age notions make it from the Bronze Age, which would now be anywhere from two to five thousand years old now, and survive to the present day, and yet so obviously imperil the survival of humanity? Should not these Bronze Age notions have caused the extinction of humanity in the millennia since?
You're leaving out the force multiplier that is modern technology. It's what Einstein said- the bomb has changed everything but our thinking.
If Hitler had had the bomb, the world would have been destroyed via nuclear winter before they could have figured out what was happening . It's just an accident of history- not a form of historical inevitability- that Hitler didn't get the bomb first and starting using it.
You're making the same mistake in thinking that people who cite the improbability of life itself as evidence of divine creation. The fact is, if we weren't here - by accident- then we wouldn't be talking about why we're here. Being here- for whatever reason including just chance- is a prerequisite to talking about why we're here.
So also with our lucky continued existence under the influence of Bronze Age ideas of God and Heaven and Hell and the supremacy of Biblical and Islamic or Hebrew law which is, how many people in the world live and evaluate morality still to this day, especially in America where half of all people reject evolution in favor of creationism and vote that way. If we had gotten unlucky in, we wouldn't be here to talk about it. Being here to talk about itself proves nothing about the current efficacy of those ideas.
So today we are facing a timebomb called global warming. It's going to go off, it IS going off and once it reaches past a certain point - a point which may be as close as 20 years hence, then there will be no turning it back, no magic technology is going to save us. 20 years is not enough time to change a conservative's "mind". We need to have started acting in a concerted manner yesterday. So this is how the conservative mind represents a clear and present danger not just to the US but to everyone in the world. It's the intersection of the rapid pace of change and the magnitude of change that technology confers on us and conservatism being conservatism.
Another way conservatism threatens humanity is the threat of conservatives in other nations getting a hold of something more deadly and far reaching than just airplanes. As nanotechnology progresses, as home fabrication becomes a reality, as our command over nature increases on the genetic level and microscopic level, as higher education spreads it increases the probability that well integrated, seemingly intelligent fundamentalists will appear in labs, in positions of power in research institutions and next time it won't be pressure cookers at marathons but germ warfare everywhere or worse.
None of this is taking into account the heedless, reckless actions of non-terrorists within our society who are motivated by pure greed and hubris who may accidentally release a pathogen or a genetically mutated organism which kills hundreds of millions before we can even understand what's happening. Or something more pervasive like the destruction of the ozone layer, which has the power to wipe out the bottom of the food web through over exposure to UV. In fact, that almost happened.
The conservative / insanely greedy and selfish mind and modern society are fundamentally incompatible. We cannot continue to permit the greedy and the religious head cases loaded down with sociopathic indifference to others to continue to exist on this earth. Full stop. Those are genetically mediate traits and it's at the level of genetics where
