People have indeed doctored the meanings of terms over the centuries, but what I laid out is a far more useful understanding. Liberalism, as an example, is the umbrella ideology around capitalism. It isn't "LGBTQ rights," the social factor doesn't really play as much into liberalism as the economic factor. Conservativism falls under liberalism.

I don't really think I described anything in a "narrow" sense, it's more broad than some may choose to define these as.
