When I was much younger, I recall a librarian who mentioned that a careful selection of words can affect thought. The example he used was of referring to his significant other as his "love" rather than just his "wife" helped reinforce the actual feeling.
The rationale behind his explanation is somewhat vague, but the idea that thought is linked to language is not a new one. Words compartmentalize complex concepts and meanings, allowing even more complex ideas and thoughts to be generated from such words. The most well-known example of this concept is presented in George Orwell's classic fiction,
Nineteen Eighty-Four, in which a totalitarian state's language is a greatly-reduced version of English known as
"Newspeak". By destroying as many words as possible while allowing society to still function, the totalitarian Oceania had hoped to minimize independent thought and make it impossible to exchange new ideas that could be detrimental to the Party.
Extending the above concept, the use of different sets of words to discuss a particular topic can have an effect on the tone of the discussion. This is the case with politics, where the language used to discuss politics infiltrated by words that carry unsuitable connotations, both purposely and inadvertently.
Overtly violent rhetoric (particularly from the U.S. Tea Party's leadership) is under the microscope after the recent shooting of Congresswoman Giffords and 17 other people (leaving 5 dead) in Tuscon, Arizona. Although the shooter himself is likely non-partisan, he lived in a society inundated with violent imagery and terminology (not limited to just politics, either) and in a place where getting weaponry was easy.
Going beyond the violent rhetoric in the U.S. that (thankfully) has yet to become commonplace in Canada, one can still find plenty of problematic language used in politics. Politicians often launch attacks on each other with no regard for the degradation of political discourse. (Remember the accusation that an opposition MP was "in cahoots with the Taliban"? There is a reason why the opposition is formally known as "Her Majesty's Loyal Opposition": having differing opinions should not be interpreted as "disloyalty".)
Language used by the media is often problematic. There are "battles" in elections, and ground is "gained", "held", or "lost" as though territory is being fought over. The media chooses these words to make their narratives sound more exciting, and in a technical sense these words do describe what is going on. However, these words are more strongly associated with warfare between belligerents, and the choice of these words may subtly influence viewers/readers into taking more hardened positions. This effect may be stronger in down times such as the current economic recession, since the public tends to become polarized in bad times anyway.
Partisanship, likely a symptom of the innate human desire to be part of a larger group, is certainly exploited by language as well. It becomes similar to loyalty toward a sports team. One day, your
team party will win the
Stanley Cup election! Of course, language used in sports also borrows heavily from warfare ("battles", "gaining
ground the zone", etc.), which makes the usage of such terms in politics even more seemingly-innocuous and subtly damaging at the same time.
Even more commonplace language not necessarily handpicked by the media taints political discourse. For example, apparently we elect "leaders", not representatives. People are elected to "power". We are encouraged in ads to make a difference by voting, but why are we not encouraged to talk with or write to our elected representatives? It distorts the spirit of democracy: the people govern themselves by selecting representatives who will do the necessary work of governing on the people's behalf. Voting is just the first step in participation in a democracy, but the implicit (and probably unintended) message underlying political discourse is that "people should vote for their desired ruler for the next few years and that's okay".
It likely even affects the motivations of people who run for office. I would suspect that those who run for office to serve the public would differ from those who run for office for "power".
Beyond just better education and trying to get people more involved in politics, I submit that the health of our democracy could benefit from changing people's attitudes through something as simple (?) as being observant about even seemingly-innocuous language being used in political discourse.
Peace and long life.
