It's a terrible way of looking at it. These words have meaning, and can be traced to their roots. The assembly during the French Revolution split itself left and right, the right side supporting some amount of monarchical power and left rejecting that. Thus, left and right became those for democracy against those for hierarchy. The two major American parties carry this legacy right in their names: Democrats, for majority rule, want to elect officials to enact the will of the people. Republicans, for leadership, want officials to act in the interests of the people with their own wisdom. That is the difference between democracy and republic after all.Thaluikhain said:Along with a shift in what is considered left and right due to social norms, that's not a bad way of looking at it.
That the parties "switched" in any way is because Democrats have moved wildly on issues, but the truth is the core principles of the Democratic party have remained the same: enact the will of the people. The Democratic Party swings on policies swiftly with the era because public opinion changes. The Republican Party has fixed principles, the principles on which America was founded, that it governs by even when it isn't popular to do so, believing that to be in the best interest of the people whether or not the people are asking for it. But that is the essence of left vs right, democracy vs hierarchy. Democrats have been the left as long as Republicans were the right, just as Democratic-Republicans (the Democrats before name change) were the left when the Federalists were the right.
