I think things like that will continue to be argued forever, because it's rarely a black and white pure facts issue.
Even if a conservative says "Death penalty is good, here see some statistics that prove it's a deterrent", a liberal may turn around and say "But
it's not humane", and what can you do? You can't really 'prove' that something is humane or inhumane, that's a personal judgement.
Even things that could be based more on facts and prior experience won't be. Something like what economic system you think is best, there will
always be some way for people to argue against you, because economics is so complex, and relies on so many factors that it's difficult to actually
prove one system is better than the other, except for totally flawed systems that have resulted in the ruin of every country that implemented them.
As a society we have to argue about these things, because they can't always be settled with hard facts, so we have to rely on other things like
emotions, morals and anecdotal evidence.
