"Every article I've read treats those who were pro-Brexit as if they were complete idiots, as if their concerns aren't legitimate."
You are using very strong language there, but it is important to remember that the pro-Brexit people were badly misinformed, and the concerns that drove them were completely illegitimate in a modern Western country. So it is entirely appropriate that the articles give that kind of treatment to the pro-Brexit crowd. Such articles are accurate and we should be grateful for their honesty and reporting.
