They are not rooted in science in the sense of sophistry where they are anti-authoritarian and anti-conformist. Its impossible to express something new without being in conflict with established authority.
Its actually a fairly normal situation for all paradigm shifts. Kuhn wrote a book about it named "The Structure of Scientific Revolutions" about a half century ago; it seems a pretty accurate model for how real paradigm change happens in societies (as opposed to idealized theory).
I'm not saying you're wrong and certainly not in any sort of value judgment but am saying that historically there seems to be no possible way for a paradigm shift to roll out without those relatively standard feelings and attitudes toward change you express.
The legacy model seems to result in sad middle aged lonely cat ladies for no obvious reason; clearly that model doesn't work well enough; the paradigm shift proposes a workable model with successful predictions, perhaps workable solutions.
