Apart from the first line, this quote doesn't apply here and frankly makes no sense. Yes, English may borrow (or steal forcefully, apparently) words from other languages, but that does not mean the language internally must not have its purity defended. Devaluating terms to have little meaning (awesome, terrible, fantastic) is not my idea of progress.
(Foreign languages on the other hand are a good source of new words which can be introduced, already inflated, into English.)
Awesome, terrible, and fantastic all have meaning. They have as much meaning as they ever have. They have different meanings, and the broadening and shifting of their meanings has allowed people to communicate with more effectiveness and nuance.
There is no inherent value in words having "strong" (as in forceful) meanings. If people do not use them that way it's because they do not need them that way.
