> You're arguing for active assurance of truth, assumedly forced on people,
No, this is the opposite of what I'm arguing for. I'm saying that if a community agrees on a definition of what truth is (the old consensus was "something arrived at via a process mostly like <this>"), then "truths can exist" within that community. By contrast, if they do not agree on a definition what truth is, then no truths can exist within that community.
I'm not using references to Foucault to talk about what I think about defining truth; I'm making those references because that's what the public intellectual underpinnings of the alt-right relies on. Personally, I think that some of what Foucault had to say is insightful and interesting, but the extension of his observations to knowledge in general is unsupportable. And not just unsupportable - utterly destructive of a consensus about truth-generating processes that in turn is vital for functioning (democratic) communities.
> You're arguing for the need for society wide consensus in belief
No, I'm arguing for a society wide consensus about how we choose between beliefs. Societies in the past have had this and still accomodated different beliefs. Most of the time this is resolved by noting that the beliefs can't be resolved via evidence. For example: what is the correct role of the state? There is no truth-generating process that can provide an answer to this question, but there can still be multiple different beliefs about the right answer.
> anyone who wanted to ban such debate
The issue is not "ban such debate". The issue is unwillingness to tackle in good faith the debate that has already taken place. No truth-generating process can involve an ever-present willingness to endlessly discard things already accepted as true. Clearly, it cannot refuse to ever reconsider either. So the actual path followed is a compromise between these two: if you don't have radically divergent and NEW evidence or data explanations for something considered settled, you'll have to wait a while. We're not going to relitigate whether the earth is round or not unless someone comes along with either major new data that is incongruous with our current "truth" about this, or someone finds incongruities within the data/"truth" we already have. That doesn't mean "debate is shut down" - it's a reflection of "extraordinary claims require extraordinary whatnot to be worthy of spending any time on".
I don't think anyone serious claims to know the cause of autism; I don't think anyone serious claims it is vaccines, which is in turn a reflection of what the the truth-generating process (the one we had consensus about until recently) says about that.
