I don't know what percentage of trump voters believe that the earth is much younger than what science has determined but I do know that a sizable portion of them are christian evangelicals (millions of them). By definition they believe in the literal truth of the Bible (a good portion of my extended family are evangelicals and they live in the US and are trump supporters).

It is through my relatives that I am aware of what goes on in that community via their facebook posts. I agree that men are men and women are women (biologically) but I also believe that everyone has the right to be addressed in whatever gender denomination they prefer and should not be discriminated or harrassed because of it. But I digress.

Have you ever considered that labeling something as originating from the CCP is nothing more than a modern variation of the "red scare" tactics used in the 1950s by politicians to discredit anyone that has a different view on the world? Since it is ingrained in the US psyche that communism is bad some politicians just need to appeal to that sentiment to sway certain portion of the population to their side even if the positions of their opponents have nothing to do with communism.
