“Why do dubious stories like these get traction?”

What I want to know is, on what basis does Mr. Coday make the value judgment that the stories swirling around the Bannon/Burke connection are dubious? I happen to believe there's a great deal there worth examining, particularly in light of Bannon's professed white nationalist tendencies which he openly expressed while editor of Breitbart. Based on everything I've read, dubious is not the adjective I would have chosen - "convincing" would be more like it.
