Liberals don't ask 'Does it work?' They ask 'Does it equalize?'
The world is a bad place. There are many wonderful people, but on the whole, humanity basically stinks.
There are surely times when a conservative and a liberal would agree. We would agree on how moral it is to discriminate on the basis of race. There's absolutely no light between those two positions. It becomes a little more complex when you talk about law as opposed to morality.
Those who don't hate evil hate those who do
Grateful people are good people, and good people are happy people
No American conservative has ever argued that the government should never be involved in peoples' lives. That is anarchy, and we don't argue for that.
