My all time favourite conspiracy theory was the one espoused about the supermodel Caprice really being a man. Absolutely bonkers.
As for the vaccine ones, it all has the smell of the cynical manipulation of aggressively ignorant fools.
For example, back when trains were being pushed as an alternative to canals for transporting goods in the 1800s, canal boat owners paid local priests to extol the Biblical evils of trains. The canal boat owners also quietly pushed mounted letter writing campaigns / pushed pamphlets against the new technology that would rival theirs. The propaganda accused trains of everything such as the souring the milk of cows, that the human body wasn’t meant to travel at 30mph, that trains caused barrenness in women, lack of potency in men, physical and mental impairment in children etc.
Sound familiar?
That the Christian denominations got behind bullshit like that then as well as pushing against modern medicine such as vaccines now should forever be a testament to what big business fear-based religion is, how much it competes with technology for power and how it’ll take any sum of money to push whatever rubbish the donor wants to spew.
