I agree that stereotypes can be used to manipulate how masses think, and I agree the media can be used to create and destroy stereotypes, and so those who control the media will be able to exercise an extra degree of control over a culture by controlling which stereotypes they believe in and respond to. I also agree that the media can be used to shape the development of languages, especially when it comes to coining new terms and shifting the meaning of existing terms. What I disagree with is:
1) That language shapes culture more than culture shapes language. I believe that for a term to become widely adopted people have to be convinced that it accurately represents a preexisting concept. "MILF" got picked because ppl needed a word to refer to hotties with kids. http://www.urbandictionary.com/
is littered with coined phrases that no one ever uses b/c they're not things people actually want to talk about (e.g. too specific, ect...).
2) That women are particularly left out of this process. Most people (men and women, both) don't control the media. Only a tiny minority does (some of which are probably men, and some of which are probably women, but this is just a presumption- they're a mostly invisible elite and we can only guess at what their demographics are). But men and women both control language in the sense that every individual person decides what words to use, what to pass on and what to ignore. If men en masse decide that "cougar" is offensive or stupid or awkward and they don't use it, it'll be less likely to catch on and become part of the language. If women decide it's useless or stupid, they have an equal ability to veto it. Language is passed and adopted from one person to one. Celebrities/media introduce words but they don't decide what gets picked up, the masses do. And men have never had a monopoly among the commoners.
Re: the religion bit, that was interesting. It sounds like you're really part of a liberal sect. Mind if I ask what? I wonder if this is more prevalent among con langers than the general population. Has anyone done any polls?
