“Left” and “Right” are two of the most commonly used political designations in this, or indeed in any, country. And you know, they actually used to mean something once. Back in revolutionary France, the “left” was opposed to the monarchy, and the “right” were supportive of its traditional structures.
In the years since then, “left” and “right” as political terms have come to mean a lot of different things. What they have come to mean in practical terms, however, is either a mark of the political naiveté of the speaker, or are used as terms of opprobrium. In actual practical political terms, they’re now effectively meaningless.
