Western civilization has benefited more from Christianity than from the ideas of Ancient Greece.
-No. Data suggests that secularized countries are better off in most aspects (equality, welfare etc).
See e.g. http://www.pewresearch.org/fact-tank/2015/03/12/how-do-americans-stand-out-from-the-rest-of-the-world/

Medically assisted suicide should be legal.
-Yes, definitely

Taxpayer money should not be spent on arts or sports.
-Disagree somewhat, but it definitely needs to be re-evaluated in some cases.

Overall, labor unions do more harm than good.
-Neutral. I'm too uninformed to have an opinion. I kinda think they have outplayed their role in modern societies. At any rate, the ideal is a free market without them

If an immigrant wants to fly the flag of his home country on my country's soil, that's okay with me.
-Sure, why not? As long as they respect the country's laws and culture

Rehabilitating criminals is more important than punishing them.
-In most cases, yes, but not all. For me it's ultimately not a question about punishing the criminal, but protecting the society. If the capital punishment wasn't more expensive than life in prison, I would favour it

It is legitimate for nations to privilege their own religion over others.
-Why wouldn't it be? Any country should see to its inhabitants' needs first and foremost.

Overall, the minimum wage does more harm than good
-Theoretically yes.

A country should never go to war without the support of the international community.
-Disagree. A country should go to war when its population agrees it should go to war

Import tariffs on foreign products are a good way to protect jobs in my country.
-Possibly in certian cases, but ultimately and generally, the populace lose out, so the answer is no

Equality is more important than economic growth.
-No, economic growth is more important. But at some point balance is required

The government should set a cap on the wages of bankers and CEOs.
-No, but they should regulate the accountability of executives and politicians

Some countries and civilizations are natural enemies.
-Lol? No

Overall, security leaks like those perpetrated by Edward Snowden and WikiLeaks do more harm than good.
-No, transparency is good

Capital punishment should be an option in some cases.
-Yes, when rehabilitation is unlikely to happen and it's the most cost effective alternative (life in prison with community work is preferable). Why burden society more than necessary?

Speculation on the stock exchange is less desirable than other kinds of economic activity.
-Not really, speculation tends to add stability and any economic stimulation is generally good

A strong military is a better foreign policy tool than a strong diplomacy.
-Disagree

It almost never ends well when the government gets involved in business.
-Disagree. The government needs to protect its population and environment

Government spending with the aim of creating jobs is generally a good idea.
-No, but it depends on what those jobs are. We're past the Keynesian era

We need to increase taxes on industry out of concern for the climate.
-Neutral, I don't believe taxes are the solution. We need measurable goals though and actual solutions (ie innovations) to reach the goals

There is at heart a conflict between the interest of business and the interest of society.
-Not really

The government should provide healthcare to its citizens free of charge.
-Yes

Monarchy and aristocratic titles should be abolished.
-No, history and tradition is beautiful, but titles shouldn't hold power

The market is generally better at allocating resources than the government.
-Yes

Free trade is better for third-world countries than developmental aid.
-Yes, but developmental aid may be required to "kickstart" the economic growth

My country should give more foreign and developmental aid to third-world countries.
-Depends, first I would like to scrutinize how the money is used and possibly re-allocate. We give a decent chunk already

There are too many wasteful government programs.
-Yes

If people want to drive without a seat belt, that should be their decision.
-No, but it's not because they should be protected against their judgement, rather it's to protect the society's healthcare resources from being wasted

Surveillance and counter-terrorism programs have gone too far.
-Yes, and how about allocating the resources to get to the root of the problem instead of observing it?

Some peoples and religions are generally more trouble than others.
-Yes

People who turn down a job should not be eligible for unemployment benefits from the government.
-Disagree

Immigration to my country should be minimized and strictly controlled.
-Yes
