It's how conservatives see themselves.
It's not how I see myself, and I identify as conservative and not libertarian.
If they don't favor using government to make us good, they are libertarians.
I guess there is something in that. My thoughts concerning light sins, that they should be forgiven under the law, is geared toward making people better. But grave sins are a different matter, and libertarians don't believe in penalizing some grave sins, while conservatives would tend to want to punish grave sins in some way with the law. I don't know what the difference is between wanting people to be good/better, and wanting a stable society. Are they the same?
Yes, then it's right. Libertarians wouldn't want to tell someone how much he can drink, if he doesn't endanger or impose on others in doing so.
Some libertarians even argue that drinking and driving isn't or shouldn't be criminal, and that crime only occurs in the event of a wreck, and that even then, if the driver is intoxicated, it doesn't warrant additional criminal charges, because intoxication itself didn't cause harm to anyone but the drunk, and the only crime is due to any harm done with his vehicle.
Many libertarians oppose any immigration laws at all, and certainly don't see Hispanic immigration as a threat. They point to the fact that the United States prospered and grew when there were no immigration laws.
It's another point of distinction between conservative and libertarian. Libertarians also prefer what's called 'isolationism,' which entails withdrawing all troops from foreign countries, and abandoning the idea that we should be 'world police,' even in the case of genocide or other systemic war crimes.
Libertarians oppose dry laws and blue laws, which conservatives support.
I'm conservative, and I don't support such laws. If someone wants to buy and drink liquor on Sundays, I don't take that as any kind of sin, but even if it is, it is light sin.
Libertarians, even in the South, generally opposed segregation, which conservatives supported.
Another example of conservativism evolving over time. You're making a great point as to how libertarianism and conservativism have become confused, since in some cases the libertarian position was more conservative than the positions held by 'conservatives' at the time. In these cases, libertarians helped conservativism to evolve into a more accurate and coherent political position.
Libertarians were opposed to McCarthyism, which conservatives supported.
Another example where 'conservatives' are not conservative at all, but more 'overzealous.' Another word for it might be 'oppressive.' Prohibition was oppressive.
In general, Libertarians opposed conservatives in almost everything conservatives supported that is antiamerican or evil, and supported them in almost everything that was good.
I think laws against prostitution and drug use are good, but libertarians don't support those laws.
Many, perhaps most, conservatives are not LGBT.
No, but LGBT people and Black people and Latino people are all included in the right of 'the people' to keep and bear arms.
A second sign of the conservative feelings in the nineteen twenties was the nation's effort to ban the sale of alcoholic drinks, or liquor. This policy was known as Prohibition, because it prohibited -- or banned -- alcoholic drinks.
Many of the strongest supporters of Prohibition were conservative Americans living in rural areas. Many of them believed that liquor was evil, the product of the devil.
A number of towns and states passed laws banning alcohol sales during the first years of the twentieth century. And in nineteen nineteen, the nation passed the eighteenth amendment to the federal constitution. This amendment, and the Volstead Act, made it unlawful to make, sell, or transport liquor.
...
By the middle of the nineteen twenties, it was clear to most Americans that Prohibition laws were a failure. But the laws were not changed until the election of President Franklin Roosevelt in nineteen thirty-two.

Yes, Prohibition was 'overzealous' or 'oppressive,' punishing light sins severely, but of course, many of these 'conservatives' were non-Catholic Christians, and they believed that drinking liquor was grave sin. It was a valuable experiment in punishing light sins as if they were grave, and what can happen when we do that.
Thank you for calling this out, this is why I posted the OP, because 'conservative' and 'libertarian' remain indistinguishable in some ways, and even when they are distinguished, it is not at all clear as to why.
Conservative thought has evolved since Prohibition. Or, what is called conservative, as your quote reflected. While Prohibition wasn't a libertarian law, it also was not a conservative law, by today's notion of conservative, and the OP here attempts to answer the 'why.' It was not conservative, because conservatives do not believe in penalizing light sins with the law, but prefer to 'turn the other cheek,' and that is not because Christ teaches this, but because it works. In forgiving light sins, people have a better chance of changing, than if we punish them for light sins.
