There&#x27;s a salient difference between 7DAs and Catholics: it is possible to be a Catholic without abandoning science and reason.  That&#x27;s not possible for a 7D-adventist.  Biblical literalism is one of the defining characteristics of 7D-adventism.  It&#x27;s the reason for the &quot;Seventh Day&quot; part of the name.  I think it is perfectly reasonable for people to be doubtful and uncertain, even fearful, of the prospect of having someone who rejects science as president.<p>BTW, another defining characteristic of 7D-adventism is their belief that Jesus is coming back Real Soon Now.  In this, they have common cause with Daesh, who believe they are doing the work of God by helping to bring about the last days.  Again, I think it is perfectly reasonable to harbor fear, uncertainty, and doubt over someone like that having their finger on the nuclear button.
