Still pondering this one, as there doesn't appear to be any standard, authoritative definition for 'Conservative.'
aCW was right about one thing, conservatives differ from libertarians (not the political party but the political ideology) in matters of Let's Get Blasted Together, xorn, prostitution, and other Onanistic activity involving private parts that is not open to life. The only distinction in fact between libertarians and liberal Democrats in these matters is abortion.
Conservatives conserve something, but one take is that you would need a host ideology before you could conserve it, because otherwise conservative is arbitrary, which is what it seems to me in my limited reading of its progenitor, Edmund Burke. Like if Burke lived in a different time and place, he would promote whatever his culture happened to used-to support, like he did in England in the 1700s.
To promote anything arbitrarily seems pretty anti-libertarian to be sure, but I also know of no conservatives who would agree that they are arbitrary, although sometimes you have to wonder when they say things like 'the good old days', because without some kind of foundation to prove that the good old days were objectively good, they just sound arbitrary.
And if they have a foundation for what makes something objectively good, then this sounds more like what in the polisci literature is called 'liberalsim'. The philosophy of freedom, and the ideology of constitutionalism, rule of law, civilian control of the military, separation of powers, independent judiciary, federalism, human rights.
ofc there are self-identifying conservatives who reject these institutions of liberalism, in favor of whatever laws they can glean or see in the Bible.
