The founding fathers did indeed want profound change and would fit the definition of Liberal that I provided. The Tories would also fit the definition of Conservative that I provided. Unless I'm misunderstanding you, I think you are trying to fit a round peg in a square hole and wondering why it does not fit. If you find yourself in that position it best to rethink your processes.
I think people very commonly misuse the term liberal.
It seems like you are claiming liberals are people who want change. That is not always the case and is not the definition of a liberal. In some cases it is applicable, but "wanting change" is not an ideology. It is only relative to the status quo, as you aforementioned. Liberalism has its own ideology that is not built upon change.
I was simply pointing out that it is not black and white, blanket statements are dangerous. Not interested in a semantics debate, although I addressed the semantics of the discussion.
