There are a number of studies pointing to the tendency of some people to hold conservative views versus progressive ones. Here I refer to cultural issues as opposed to fiscal because it is clearly possible to be a frugal liberal and not have it be an oxymoron.After observing society over the years, the overwhelming conclusion one reaches is that fear is a major driving factor. People who tend to be fearful of change are more prone to hold conservative views and when that is paired with lack of intellectual curiosity and education, we can see how difficult it is to dissuade them from their deeply held but often erroneous conclusions.
Human history is replete with resistance to cultural progress and yet at each flash point these same people do not recognize themselves within it. The civil rights battles to defeat segregation used much the same argumentation against black people as is now used against LGBTQ people. Before that it was resistance to women voting and so on.
The remedy of course is critical thinking and education both of which are perenially in short supply. So we will wait this latest moral panic out until the next one rears its ugly head.
