Many on the Left are fairly open about this, and even proud about their enlightened stance on these "difficult issues". But, if an opponent (Sarah Palin)talks openly about it and indicates that the Left's position is morally wrong, then the Left gores ballistic, denies the whole thing, and engages in the politics of personal destruction.
And when the smoke seems to clear, the Left goes back to calmly telling people that children and old folks have got to go.
