I used two sources, the dictionary and Kasz's political spectrum.
I'm not even going to bother defending Webster's definition of conservative, I don't even know where you can bring that part of your argument to.
Do not confuse social and economic issues. There are two dimensions on these issues and four possible political philosophies, right wing conservative, left wing conservative, right wing liberal, and left wing liberal (excluding centrist of course). Because America is a two party system, we tend to think one dimensionally in politics, with Republicans on one side and Democrats on the other, and more extremist views extending out from them. But that simply isn't how politics work. Just as watching a movie in 3D gives you more detail than watching regular movies, thinking about politics in more dimensions will give you a better idea of the big picture.
