Amos, your examples have nothing to do with science and everything to do with the smug stupidity of some non-scientists, no matter what they call themselves.

BTW, I notice too that Semmelweis ex. is 150 years old, the Harvey exx. even older than that. I can't recall any twentieth- or twenty-first century scientist receiving remotely similar treatment either by a few by the scientific community in general.

That community wound up accepting the discoveries of Harvey, Semmelweis, Darwin, Einstein, and many more.
