>How far is "too far", and why?
For me, "too far" is simply when people try to change the language for frivolous reasons. I'll admit that "frivolous" is somewhat in the eyes of the beholder, but I'll use "niggardly" as an example. To me, this is a wonderfully descriptive word which connotes much more than mere stinginess and yet comes up short of miserly in that it lacks bad intent. It troubles me that we have to give up this word because of others' ignorance and/or ill behavior.
Another example is "business-speak" and the verbing of nouns, which was much discussed here earlier. In this case, I object to the creation of new words (where perfectly serviceable ones already exist), often out of just plain laziness. I would cite (if memory serves) the recent post which asked for a better word for the creation of a product than productize!!
Anyway, I would expand this argument to some of the words which have come out of the women's movement. What is inherently wrong with the word women? What could be more descriptive and (for the great majority) less pejorative? I think that most readers just react negatively to "womyn" and other such attempts. (I also, I hasten to add, abhor Rush Limbaugh's coinage "feminazi" :)
I considered posting this reply anonymously, because of my "history", but thought better of it since that would remove some of the context.
