There are people that get that obsessed over other shows as well, I think you're just trying to hard to understand brujon. I really doubt that there's any way someone could explain a hardcore obsession in a way that someone who didn't feel like that would understand and get it.
That's precisely my point. Something so weird that cannot be explained to others is unhealthy, it's beyond just not being normal. I bet most of the people here at some point have gotten flak because of their D&D hobby at some point in their lives, be it at high school or later/earlier periods in life. But it's not something that can't be explained to normal people. It's an unusual hobby, because there's not that many people that are into it, but it's not so weird. But how can you explain a wall made of Hatsune Miku papers, with dozens of Hatsune Miku figurines enshrined throughout the room, and your entire music librabry consisting of Hatsune Miku songs and remixes, while you yourself try to mimic her style as much as you can, going so far as crossdressing as her? Substitute Miku for My Little Pony, or anything else. It's beyond not being normal, it's plain unhealthy...
It's like this one girl i saw on T.V the other day. She was a hardcore, die-hard Justin Bieber fan. Everything about her was about Justin Bieber. She even cut her hair in order to try to emulate him. She was bullied at school, no one wanted to be friends with her because of her unhealthy obsession, and yet she continued to increase her obsession and call herself his #1 Fan, until she was noticed by some T.V Station that arranged a meeting with him. But do you feel it's normal to make your whole life about something to the point where you drive friends and family away, kill your social life, and become a complete alien to society?
I get strange and secret hobbies that people have that reflect their individual personalities, etc. What i don't get is people that have obsessions so great that they think it's ok to do their utmost to reflect their obsession everywhere in their lives, and Bronys are one of the hardest to understand, in my opinion, because it's a kid show, and it's targeted at a female audience. It's alien to see grown men that not only like but worship the show...
