I highly disagree that's the definition most the world is using. And I think whoever wrote that Wikipedia definition is an idiot.

Also I note you had no arguments to make as to the factual inconsistencies of that definition.

Here's another Wikipedia quote

Until the Great Depression and the rise of social liberalism, classical liberalism was called economic liberalism. Later, the term was applied as a retronym, to distinguish earlier 19th-century liberalism from social liberalism. By modern standards, in the United States the bare term liberalism often means social liberalism whereas in Europe and Australia it often means classical liberalism.

Our liberal party very much matches that, they don't like taxes or unions, and love businesses and deregulation.
