Everyone knows “words matter.”  It is easy to forget that who else is using the same words matters too.  Everyone who shares an argument creates connotations.  I’ll give you a personal example before I move on to the log cabin republicans and other issues.

I have an ex-brother-in-law.  One of his explanations for why he left his wife is that he just did not find non-blonds sexually attractive enough.  So six children and the time together meant less to him that someone who could make a convincing bleached blond, as he once explained it.

I have some understanding.  While I like the look of red hair, I find it anti-erotic.  Very strongly anti-erotic.  If I had married a red haired woman, I would probably be childless today. But when I hear arguments about how sexual attraction is essential to bonding and satisfaction, the arguments are contaminated in my mind by my ex-brother-in-law and the number of men I’ve know who traded in their wives for younger models.

The argument in that context has become the victim of semantic contamination.

I’ll give another example that applies to people in the Church.  The Ensign appeared to have a goal of an article a year or so on depression. One of the themes that they want to communicate is that while situations and environment can contribute, most depression, especially suicidal depression, is a physically based mental illness.  Most suicides are not morally culpable (meaning that committing suicide does not equal damnation).  That is a solid meme.  It occupies and controls space in the LDS frame.

When there is a suicide and someone tries to place blame for it, many people hear the message “he was driven to suicide, killed himself and is now damned and it is your fault.”  That translates further to “I’m blaming you for his sins” and “depression is morally blameworthy, not a physically based mental illness.”

As you might expect, people who make blaming arguments get the response “quit being histrionic” (perhaps in kinder tones) or “quit being silly.” The mental illness meme, strongly adopted to comfort the families of suicides (and confirmed over and over again as true by the Holy Ghost to those who provide such comfort) creates a contamination when someone tries to assert that a suicide is not the result of mental illness.

Closely allied to semantic contamination is context contamination.  Take “Don’t ask, Don’t tell.”  39% of the people who exit the military under DADT are women accused of being lesbians who have no impact on combat units, nothing to do with community showers, and whose orientation surfaces in the context of their being victims of sexual harassment (women are far less than 40% of the military population). 50% of the DADT exits are racial minorities (racial minorities are about 30% of the military).  That context contaminates any discussion of other reasons for enforcing DADT.

If you want to speak to people, and be heard, you need to use arguments that are not tainted with semantic contamination.  If you want a policy to be accepted, you need to fashion it so that in application it does not have significant impacts that are clearly outside of its proposed application and rational.  Purity is as important for virtue or power in argument as it is in every other sphere.
