I'm sure it would be right and true to find the socio-economic structural reasons
take creationism - There is a rough consensus that this is a discredited and unhepful belief. Now can you imagine you had a world leader who supported, encouraged, and didn't opposes such a belief in creationism. That is exactly what trump has done with the far right lunacy. I am saying the narrative will change that he is gone. These people will have even less credibility than they already have. All things need to be understood on a structural level, but that applies to the top as well as to what is screwing people at the bottom. Trump was an evil puppet master. If the next set of Republicans start courting this shit, and courting it seriously, then yes, we are truly fucked.
