Why answer, when you have obviously decided that "conservative" means your definition of "conservative", and that anybody who doesn't meet your definition doesn't belong on FR? By your definition, Laura Bush, Barbara Bush, and Condi Rice would be unwelcome on FR, because they don't qualify as "conservatives".
The framers of our Constitution were very much "libertarians" by today's popular definition of that term. Among other things, they didn't believe in government confiscating the fruits of some people's labors to give to other people, or regulating what people do with their own real and other private property, they didn't believe that government was responsible for ensuring a pleasant outcome in each citizen's personal life, and they didn't believe in "gun control". They didn't say a word about abortion.
The framers of our Constitution did not address abortion because it was not medically viable at the time (also, the framers did not address space travel for similiar reasons). In the 18th century death of the mother was a frequent side effect of abortion.
Our entire society was birthed on the notion that we are endowed by our Creator with certain inalienable rights, such as life, liberty and the pursuit of happiness.
Life.
The right to life.
I'm certain beyond a shadow of a doubt that the framers of our constitution, the fathers of this nation, would not be in favor of snuffing out innocent life in pursuit of whatever.
