"Conservative" is pretty much a meaningless term now, especially if it's interpreted literally. What does anyone want to "conserve" about the current political order? If anything, people on the Left are the literal "conservatives" in this day and age.
I don't really know what the more accurate label would be for people like us. Something along the lines of "constitutionalist" or "originalist" maybe. But even these terms fail to properly identify our defining characteristic, which is the belief in inalienable natural rights for every individual and the obligation of government to respect and defend those rights.
Ironically, "liberal" is probably the best descriptive term, and I figure it is no coincidence that the word was co-opted by people who are anything but.
