With that attitude, maybe we should declare that the current manpower on the International Space Station to be the last mission, and when that crew leaves, have them shut off the lights. With that attitude, there’s no more reason to look at the sky and wonder what lies beyond the orbit of our moon. There’s no hope that our descendents will leave Earth in a few billion years when the sun expands to a red giant and turns this planet into a dead rock, if not totally vaporizing it.
I miss the days when conservatives had the stones to do more than bitch.
It is not a defeatist attitude, it is realism.
