The rise of the Internet enabled many things, both good and bad.
One of the bad things has been enabling the creation of centers of misinformation, in this case, misinformation about the side effects of various vaccines that have been approved for safety by the FDA. These centers of misinformation will exaggerate, confuse and outright lie in support of their big lie, which is (in this case) the lie that vaccinations are responsible for various and sundry ills among the general population, usually claiming that they are responsible for autism.
That there is no whit of credible scientific evidence supporting their claims is considered as “proof” of a vast conspiracy dedicated to taking your money to spread autism. WHY anyone would do this is not explained, nor are such things as times and dates of use/disuse of various substances in vaccines, nor is the concept of an adjuvant explained clearly, these places just exist to confuse.
As for me, whenever anyone starts explaining how a “vast conspiracy” is doing anything, I stop listening. Vast conspiracies don’t exist, for the simple reason, known to any child, that the greater the number of people who know a secret, the less likely it will remain a secret. A “secret” known to a thousand people will be a secret for a very short time indeed.
No, Kennedy was not killed by a conspiracy involving thousands, vaccines aren’t being created with additives meant to spread mental disorders among children, and chemicals to kill off the USA aren’t being added to jet fuel (chemtrail crazy stuff). These things would be widely known and on the national news within hours of the plot being hatched.
A whole lot of gullible people need to flat out GROW UP!
