While I can see that you might experience these as uncomfortable parallels, there is a big difference you could consider: That climate activism is based on scientific research.
The cigarette lobby used science to question the link between smoking and cancer.
Try looking up "Most Doctors smoke Camels" to see how much we can trust the experts who only have our best interests at heart and would never tell falsehoods for a payday
> climate activism is based on scientific research
Yes, but often “based on science” like biopics are “based on real events.” Activism presents no error margin whereas the actual science does, and very often activism extends into alarmism where it presents end of the world scenarios which the science doesn’t present. Activists too often present the future scenarios assuming no adaptation whatsoever, like a flooded Miami where no one has moved to higher regions. The science itself is increasingly skewed too, such as the recent forest fire study where larger drivers of forest fires like arson are ignored in order to make publication more likely.
based on scientific research, much like communism and scientific management and phrenology and racism. meanwhile climate models are not capable of predicting the past given current conditions, produce wildly incompatible results, and operate on a model of the earth that is pathetically simplistic, ignoring cloud coverage (which has 3-20x the magnitude of effects of carbon) solar variability and wind patterns. the world might end as we know it for it is clear that crucial features of the earth are changing at a rapid pace, especially oceanic currents, but it will happen in a way that completely surprised most people, if not climate scientists that are aware of the limits of their models.
> ignoring cloud coverage (which has 3-20x the magnitude of effects of carbon)
This is like complaining that tidal models are useless because they ignore waves, which have a larger effect on water height than tides.
(The same analogy applies to claims of the form "how can we possibly predict the climate decades ahead of time when we can't predict the weather 2 weeks from now")
Racism is real. And crt provides good insight with high degree of predictibility as to how our system of laws work to assist existing racial inequalities.
In any case, this feels like you're building a strawman.
