"Therefore, All the "source" singers that you put on pedestals, are in fact revival singers, the very group of people who are ruining the traditional scene in this century."

No, they aren't. The term 'source singer' has an accepted meaning, examples include Harry Cox, Doug Wallin, Addie Graham . . . these people are NOT revivalists in any sense of the word. Whether someone prefer to listen to a given source singer, or another who is a revivalist is another, separate question.
