No, it isn't the definition. As you have been shown. Any who have been cancelled have been because they're a danger to humanity, much like RFK Jr., who, ironically, has cancelled many legitimate scientists.
Again, this is why we don't just simply stick to anecdotal evidence. I had unvaccinated extended family members who died and almost died from Covid, and know many others who knew people who died from Covid. I only know of one person who reacted poorly to the vaccines and so stopped getting them.
I trust science, not pseudoscience, because I trust in God. The problem is that you falsely believe science is pseudoscience.
