Fandom bonding?

From an article on the rise of bromances between straight and gay men, I found an unexpected quote:

"Mr. Gregory, the Irish author, thinks that one connecting point for the younger generation is the proliferation of geek culture. “It’s technology, superhero movies, Pokémon Go and even some indie rock,” he said. “They’re all part of an often male culture that young gay guys feel part of, too.”"
