This idea needs to be put to rest. Shine the critical light of examination on this "belief" that the most reliable way to expose bad ideas is to expose them.
Have you seen this tested? Have you evidence that this works?
Crucially, does this work at internet scale or in social medai-esque content environments?

I can say that we know for a fact, that exposing conspiracy theories by letting people broadcast them independently is a sure shot way of having them infect more people.
We've seen this evidenced all over web forums, and social media. Bad ideas get amplified. Worse, the more complex the logical counter argument, the far better the bad idea will fare.
Here are what we know, for certainty:
1) People DO NOT want to spend cognitive power.
1.1) Content that forces cognitive expenditure will gain fewer views and therefore be harder to go viral.
2) Emotion driven processing is cheaper.
2.1) Therefore emotion engaging content will proliferate
3) this is worsened over general demographics
3.1) Proofs or logical arguments that require more than common knowledge will need novel approaches to propagate.
Our human web of knowledge is a growth medium that suits conspiracy theories, self referential beliefs, and superstition.
Reason is the interloper here.
