Republican science is a fraudulent construction detached from reality (see, for example, “climate change,” “human sexuality”), created to support the goal of rich-richer-poor-poorer by marshalling hate and fear to cause distraction.
It is a misdirection play on a grand scale.
The Commander Guy describes the dynamic quite well. A snippet:
Note to Wingers: (1) Rightwing mythology keeps the rubes confused and angry. That is what it is for. (2) You don’t need to believe it to use it. (3) When confronted with truly toxic rightwing mythology (as a Republican candidate–ed.), you either need to bat it down forcefully or pretend you are unfamiliar with the specifics of the particular myth but will look into it.
