Does it matter that they lied? This is the proposition that can be debated sensibly and rationally - but will likely be overwhelmed with emotion.
In my own observation there seems to be rather a lot of people who have almost no faith in their fellow humans and believe the only way "people" believe a thing and will act is because they have been told to believe it by someone. Misinformation takes all the blame in this paradigm. The populations is dominated by people who have outsourced their critical thinking.
It may be true, I don't know. But it seems to me to be really quite worrying if a population has to be told lies to get them to do the right thing or lies have to be censored because people will not be able to assess competing evidence and reject bullshit. Does it have to be this way? Was it always? Is it fixable? Is it really a thing at all? I have no answers there.
It's my observation that even in the service of "good", the debt to the truth always comes due and the interest rate is super steep. Many will disagree.
