These are really hard to completely overcome. Number 1 especially. What we are told by what we see as authority figures when we are young and impressionable is practically permanently tattooed to our brains.

For example, those of a certain age may wake up to the malevolence of the covid vax, but polio and smallpox vaxes? oh no those MUST forever be saviors of humanity.

Same thing for trying to wake people up to transgenders. Big Mike - sure. But try to point out people from the so-called golden era of Hollywood and country music? Close to impossible to wake people up to that if it shatters childhood memories.
