A certain generation think they invincible and will never take the risks seriously -
I beg to differ. I see a lot of 'older' people spouting conspiracy theory garbage. It is a coalition of anti-vaxxer/anti Soros/anti-deep State lunatics who think they (and they alone) are the keepers of the truth whilst everyone else is castigated as sheep.
Its an offensive by a coalition of the credulous. Full-on nutcases are leading the charge but they are helped by the multitude of functional illiterates who thrive on social meeja.
This public stupidity is not a new thing. It was first studied by US Intelligence Agencies back in the 1950s when they used it to create (among other things) the 'Flying Saucer' hysteria and reinforce their anti-Communist agenda.

Note that the aim of all this is not to make everyone believe the latest crazy lies but rather to condition the not so nutty people to seeing many contradictory claims. To confuse people so they do not know what is real and what is lies so they stop accepting
any explanation. It appears to be working and there are a number of studies on Conspiracy Theorists about that describe the personality types who believe this garbage. It appears to be mainly projection. Because the people who believe conspiracy theories would have no hesitation lying and making things up to further their agenda then they are willing to believe the other side are making the stuff up as well.
