Liberalism can’t “do” anything one way or the other; it has no agency, being a variegated body of political thought developed over centuries.
– Matthew Sitman
Expanding on the Mr. Sitman’s point, neither can conservatism. (The context for his comment was a complaint about the state of the world and that liberalism hasn’t produced a better outcome.) Liberals and conservatives can do things – or not do things or act to prevent things from happening, as they are so included. Politics is a maker’s endeavor not a consumer activity.
