I’ve been acquainted with one brony about 10 years ago. The guy, who appeared to be late 20s, worked tech and looked like a typical hipster with beard, beanie and smoked a pipe.
He was a loner. I’d think most of these brony types are loners.
We have a self-admitted Brony as a Freeper. I forget his handle. He seems like an okay guy. I'd be curious to hear his take on the right wing extremist narrative.
