This is the most confusing thing I think I have ever witnessed, this might be the most baffling internet phenomenon in the past 10 years. I honestly think you guys managed to some how trick yourselves into enjoying a show that has absolutely ZERO entertainment value, I say that as a guy who was forced to watch a few full episodes because their little sister wouldn't relinquish the television. Before I even get to the reasons why this show has no entertainment value, I will first hypothesize how on God's green Earth it came to this. And before the taste argument comes up, I'd like to say there is a difference between enjoying something odd like calamari that not everybody likes, and then enjoying licking shit up off the ground and calling it your preference.
The entertainment phenomenon that is MLP: FiM and its cult following is one that is steeped in psychosis and the result of a mix of social and behavioral aspects. The largest of which being the outcast mentality aka the art of enjoying something completely outside of mainstream society and trying to make it your own.
I submit that NONE of you would have ever actually watched this show if it you had seen it on TV first instead of finding it online. I think that the only reason this show has any weight at all and any kind of following is the fact that a following actually exists, because of how much hate that said following gets, people are attracted to it because of this hate, they see it as a place for outcasts and weirdos, freaks and geeks alike to share a common interest and it doesn't really matter what that interest is. MLP started as a fad going as far back as 09 that people claimed they liked simply out of sheer irony, kind of like how some high school kids wear Dora the Explorer backpacks and Barney key chains, its just to be ironic. Then the most baffling thing in internet history happened, the irony received so much backlash (the intended result of doing anything ironic) that it evolved into a legitimate following because of all that backlash. And it makes sense, the MLP following is something anyone can join and be a part of whether its because of irony or a willingness to belong to something.
My own brother has fallen into this and I've been watching him closely as a result, he's not very social and has had many other odd hobbies, but this one takes the cake. I'll note that he never actually watches episodes, just reads about it and reads fanfiction on their website and then occasionally tries to watch an episode before I walk in and he embarrassingly changes the channel (but I could hear the voices so I know anyways). Which is good, I suppose, that he can still at least feel shame.
I know this fad will eventually die and I know my own brother will probably stop soon before then as soon as the next phenomenon rears its ugly head but until then, I will continue to be bewildered at this social oddity.
