Hearing what got you to change over from disliking to liking would be interesting to hear, and I think it might give some people insight into something they may not be as familiar with.
Ok so I guess I'll just explain how I became a brony from the very beginning so you'll be able to understand me and why my opinion changed.
I first discovered mlp about 3 years ago. By I didn't know it was "my little pony" I thought it was just something someone had made up. Like, I knew that my little pony existed, but I didn't know about the new version of it. So, on youtube's main page was an mlp related video called "epic cupcake time" and I thought that it would be funny since it was ok the main page for all youtube's to see. I watched it and I was confused a little because I didn't understand it all. I didn't particularly like it nor dislike it. I never really thought about it again. This was fall of 2011.
Spring of 2012 comes around and this is when I discover "ytp" on YouTube. I watched all sorts of ytp because it was funny. I particularly thought that the ones about Mr.Volcano were really funny. I don't know why. But there were links to mlp YouTube poops and after watching a few is when it hit me that this was my little pony.
It was weird to me so I kind of avoided watching mlp ytp. I didn't like it or I felt too insecure in my masculinity to watch it. Mind you I still has no idea of the concept of "brony" yet. I just knew that there was a show and obviously somebody watched it t make ytp videos.
Summer 2012
I went to a summer camp. They take videos of activities at camp and make a "highlights" video for each day. Someone on the tech crew added ponies in the highlights for some reason. But that's when I then later met a brony who recited the names of several ponies. I thought he was weird. I didn't know of bronies yet still. I just knew that THIS DUDE watches mlp. "What a weirdo right?"
Late summer/early fall 2012
I was watching some Rhett and link videos. I had very recently discovered this YouTube channel due to a video about bacon rubbing. In one of their GMM videos, they talked about bronies. In the video, one of them mentioned something about a one hour documentary about bronies. So out of curiosity, I watched the documentary which basically gave me a description of mlp, older generations of mlp and why they all suck, and about bronies. By the end of the video, I was skeptical because I had interest in watching it and at the same time I didn't want to. I didn't feel like I had a secure enough base in my masculinity to even watch it. But I ended up at least trying the first episode. And I was making fun of it the entire time. It didn't really meet the expectations that I thought it would have based on how the guy in the documentary described it.
But I watched the second episode because it was a 2 episode arc and if you watch the first one, you have to watch the second one. It featured a song. And I hated it. A lot. I absolutely hate singing when watching a television show. Singing and random laughing for no reason. I hate those. And you know what the song was about? Laughing. I absolutely hated that. Enough that I was rooting for the bad guy to win at the end and take over the world.
But finishing the episode, I just thought about how stupid the show was.
But the next day..... I watched about 3 more episodes.
And then over about 2 weeks, I finished the 26 episode first season. I really disliked a decent amount of it, but I kept watching it. I wasn't masculine enough to admit I was watching this. I kept it a secret.
During the time I was watching this, I was also looking a little for some brony musicians. Because I'm the documentary, a song was played and I actually really liked it. It was dubstep made by a really good musician (who still makes music today but not about ponies. His name is Alex S and he is really good.) so I really liked a decent amount of brony music. That's kind of what kept me watching the show. I liked the inspired music.
So I watched the second season in about a week. During school. This season had stepped the game up a bit. It was different. Had a different vibe. It had shifted from "directed at kids" to "general audience" even though technically it is still a kids show on a kids channel. I had actually liked the second season and found myself wanting to listen to all the brony music.
Late 2012 - mid 2013
This is when the third season began to air. I followed it closely and loved it. I came to terms with calling myself a brony but I still wanted to hide it. I literally only told one or two people I trust.
I kept listening to brony music a whole lot. I listened to music all day every day. And even when falling asleep.
Late 2013
Season 4 began and I followed it. I had also began producing music. I made one mlp related song.
2014
I got mlp merchandise. 3 shirts, a blanket, a poster, dog tags, a lunch box, wrist band, socks, and mlp collectible cards. By this point, I'm obviously in love with this show.
I had actually experienced something in the brony fandom called a "pony high"
This is when you want literally everything ponies and you are basically obsessed with mlp. Typically lasts about 6-10 months. It lasted for about a year and a half for me. And now I'm still in a pony high but it's a lot more mild. I still like poni died this and that but not everything has to be.
I used to have 80-90% brony music with a library of over 1000 songs. Now I listen to about 10-20% brony songs.
I used to think about mlp at least all day everyday. Literally. I thought about ponies in every period of class at school. And all the time at home as I surrounded myself with pony music
Now I think about it daily but not literally every second. Just many many moments a day.
I'm also not as secret about it anymore. I've become more secure in myself about being a brony.
I also don't make pony music. I make regular music. But that's a different topic. I never actually really had a desire to make a lot of pony related music.
