Let me comment on this:
This is often referred to as the "Frontier thesis" of American history. While there are elements of truth to it, it's not the whole truth(which is too complex for me to elaborate on here). This view has been very powerful in liberal and progressive circles, and its influence is to be seen in that many conservatives even believe it today - which in itself points to a larger problem conservatives face.Indeed, the very term “American conservatism” is something of an oxymoron. For most Europeans who came to America, the whole purpose of their difficult and disruptive journey to the New World was not to conserve European institutions but to leave them behind and to create something new, often an entirely new life and even a new identity, for themselves.
