herbie herbie:
We can't
it's too expensive
the fuel cells for the starships are at least 15 years away
only socialists want to colonize space
it's not in the 10 commandments
there is no space, it was all a Hollywood backlot
they haven't lowered the grades to C minus to make astronaut school, it's not fair
white men aren't allowed to be space travellers anymore
we need the money for more bombs
it should be privatized first so I don't have to pay for it
I ran out of things to whine about

It's all just versions of the objections to every other great endeavour of man:
Can't cross the Atlantic Ocean because the world is flat.
If men were meant to fly they'd have wings.
We should not be going to the moon when we still can't cure the common cold.
The sound barrier will never be broken.
The automobile is a passing fancy of the rich and it will never catch on.
Big deal that the Russians have a satellite, what use is a satellite anyway?
Electricity is simply too dangerous to have in people's homes.
