Eating the rotten meat has wrong thinking ahead of doing it
As does ignoring the vast amount of data, from innumerable independent sources all around the world, proving that the Covid vaccines are safe and effective.
If you are going to form an opinion on something, when why would you disregard the evidence?
The answer of course is that your opinion against the vaccines was already formed before any data were available. Which then leads you to desperately cherry-pick (and divest of context) anything that you can to prop up your preconceived opinion. This is wrong thinking. Right thinking, when confronted with data that challenge your opinion, is to investigate, not to bury your head in the sand.
