Challenging orthodoxy

At any given moment there is an orthodoxy, a body of ideas of which it is assumed that all right-thinking people will accept without question. It is not exactly forbidden to say this, that or the other, but it is "not done" to say it ... Anyone who challenges the prevailing orthodoxy finds himself silenced with surprising effectiveness. A genuinely unfashionalb eopinion is almost never given a fair hearing, eithe rin the popular press or in the high-brow periodicals

George Orwell

As we all know, "the more things change, the more they stay the same."
