Oh? Really? Then why don't you prove you're a conservative by defining it for us?
Conservatism is made up of three (really four) distinct factions:
Fiscal Conservatism

http://conservative.org/found-conservatism/foreign-policy/ (long, but good)
and the fourth, usually lumped in with fiscal, civil-libertarianism, which, rightly defined, has little to do with fiscal matters. It is not easily referenced, but springs from Goldwater, and is hallmarked by constitutional constructionism. federalism, states rights, individual liberty, and can generally be considered to hold foremost the conservation of the literalist view of the Constitution, and the separation of powers as defined and resulting thereof.
Conservatism in America rises specifically out of the Goldwater wing (read far right wing) of the Republican party, unlike Neoconservatism, which arises from the moderate wing.
Conservatism is defined by (one is a conservative if one has) adherence to the principles of at least one of those factional groups.
Reagan Conservatism is defined by those who embrace ALL the principles of all the factions, with the emphasis toward meeting the basic principles of every faction, rather than throwing any faction 'under the bus' wrt compromise, especially wrt election.
The only other conservatism falling within Conservatism itself is PaleoConservatism, which, by it's original coining, is just pre-Reagan Conservatism... the three legged stool as it originally stood... Fiscal Conservatism, Defense Conservatism, and Goldwater (Civil) Libertarianism sans Social conservatism.
