My interpretation was many as in "the vast majority", which would qualify for "put an entire generation". Of course you can't have every single person fall under such a category, this is absurd and you are deliberately not giving me the benefit of the doubt just to nitpick.

But in any case, is this even true? That this generation of 20 something, as OP said, "can't speak for themselves and are overly shy"? That's my gripe. I don't think it is, at least not in such an immediately obvious way. Hope it clarifies. If it doesn't I can only wish you a happy life.
