@Setanta,
Yes you did make a logical leap!
You are arguing about how words should or should not be used relative to how it was used, or it is used in the past?
Sure language has power, but does it have worth or currency as you say?
The only example of debasing the English language is barbarous jargon.
It is more than the debasement of the language, it is the familiarization of the culture. Children talk to their parents as though they were talking with their school mates. There is a lack of respect for those we do not know by immediately treating them as long time family friends instead of with the courtesy of distance until both sides are willing to change the relationship.
I know where you are coming from.
Edwin Newman fought the good fight over misuse of the English Language. We do, however, appear to be in a state of decline: nouns are used as verbs, "then" and "than" are used interchangeably, and editing seems to be a thing of the past.
But also remember that language, especially English, is living and constantly evolving.
Shakespeare invented words as he saw fit and enriched our language tremendously.
However, there is a difference between adding to the language and misusing it.
And your examples, well it is hard to say if whether the people are misusing the words, because the context of the situation is not given.
