‘But always remember that conspiracy theory is a symptom not the cause.’
It is a reaction not a symptom. But now it is easy for governments to give out half truths and let the conspiracy theories make the rest of the case for them.
An example here is how incompetent our government has been in dealing with Covid-19 and some spent so much time instead concocting theories that it was just the flu, not only condoning actions by extreme right wing governments, but ignoring or even condoning their actions. We now have the major consequences of clamping down on dissent and secrecy in contract award produced by this emergency, and the anti- Vaxxers and Covid denialists have no comments to make.
