"not necessarily reliable" is a very big dodge, often the dodge of last resort applied retroactively to smear people against the party line. People like James Watson, involved in the discovery of DNA, suddenly become "not necessarily reliable" when they say something culturally inconvenient about IQ.

Or in ye olden days with Dr. "Please wash your hands after an autopsy before you deliver babies" Semmelweis gets labeled with:

"These are my impressions of Dr. Semmelweis's experiences; for these reasons I must judge provisionally that his opinions are not clear enough and his findings not exact enough to qualify as scientifically founded"

Thanks a lot, Mr. Critic! I'll take my newborn baby with a cadaverous infection to go! Yaas consensus science, queen slay!

The preponderance of the evidence for all of the above are so strong that any normal citizen would get convicted of the death sentence on them. Any appeal to epistemology of, "it depends on what the meaning of ‘is’ is" Bill Clinton level trash is weaseling in the face of obvious evidence. Of course, the political elites have always been able to dodge any justice with that bare minimum effort, so I suppose you are well justified in bringing it up for their defense. It works, after all.
