Atheists, at least in my own observations, value the awesomeness of life and the potential of humanity, and they care about making life better not only for themselves but for other people, including those in the future. A disconcerting number of deists have the destructive mentality that everyone who does not hold beliefs identical to theirs are evil sinners and deserve only hell and pain; that taking care of the future of life here is not important because they'll be going to a sweet afterlife and besides, screw the sinners and screw this rock we live on; and the most troubling of all, if they repeat a couple empty mantras, they have free license to be a total douche and still be rewarded for it.
They also are more likely to believe falsehoods just because they WANT to believe them, and unfortunately they enjoy hating things and LOVE to hate other people. This has the potential to be extremely dangerous to not only a nation but to the rest of the world. I am reminded of the Fox propaganda machine and how appalling that it is not only viewed, but the rest of us are just letting it continue to lie to the mentally feeble and to constantly motivate them towards a movement of violence and destruction. ( Consider also that some in our government are part of an offshoot of the Christian religion that believes it's the wealthy and powerful who are God's favorite people, and they are totally God's BFF even if they're dictators who massacre their own people by the thousands. That's totally the kind of faith I want in my government. I know this is by no means true for every deist and there are cool ones, but by putting "GOD GOD GOD" on everything, not only is it alienating to everyone who is not Christian or Catholic, it's allowing the whack job fundamentalists to believe they are further entitled to slow down the progress of the rest of humanity.
I would rather we just acknowledged as a whole that life is pretty neat and important, and whether or not there is a God, It would be way more impressed if we were being decent human beings on our own--not because we thought we could trick God into thinking we're good enough to get into heaven by appealing to Its curiously human ego. Don't get me wrong, I think religion has served an essential function in humanity's advancement, but religion must evolve as humanity and society does--or else we will become stagnant and mad.
I suppose I am just an idealist because I feel that given the vast amount of wealth, advancement, and potential available to all of us but had by only a handful, we could get over our primitive pettiness and understand that quality of life for the individual is very important and is something that affects all of us, and for even the most selfish of us to realize that our success this far has been dependent entirely on cooperation balanced with individuality.
But there are those who would rather own all the caves than share the future of possibilities.
