I have always found this type of behavior perplexing as well. I had a Kickstarter campaign a few years ago and one of my backers latched onto me like glue, he was repping and praising my product like it was god's gift to man, incessantly for weeks on end. It was flattering but also a bit confusing. I scrolled through his FB wall the other day and see that over the years he's done this pretty much over everything that's gained some traction in the media. He became a "bitcoin zealot" when that was popular, he became a AI fearmongerer, now he's a Trumpian provocateur. There is no cohesion between any of these identities other than the fact that they are reflections of what's popular at any one point. To me it's facade he's constantly draping over himself but to him that is identity. I think humans are evolutionarily tribal and naturally some members are going to be more dogmatic than others. Myself not exhibiting that behavior, it's somewhat odd to observe from the outside.
