I get that. And I say live for your passions no matter what (unless they are detrimental to others)
But what is it about mlp that makes you a fan? 
Let's hope I don't turn this into a long wall of text.
Anyways, it's a question I get a lot -- same with most bronies (one of the terms that refers to fans of the show that are male) -- and it's usually a long answer. I first started watching the show during a field trip for an out-of-state computer science competition for my highschool a few months back; one of my good friends, a former member of the team who was hitching with us on the trip, was talking all about ponies, and was even wearing a fedora with tons of paper pony cutouts pasted on it (which at the time I thought was rather odd
). Well, rather, I started watching them that night. I was in a room with 3 other team members playing some game on the Wii they brought with them well past midnight so I started watching the first 4-5 episodes then (the first 2 sucked, but after I got through them, they were surprisingly good). Another reason I started watching them was that another friend gave me a link to
SHED.MOV and
A Cupcakes Trollvid (both NSFW) and after watching them I decided to see what the actual show was like. So, fell in love with it. Got through season 1 in about 3 weeks, then moved onto season 2. Also joined some pony forums, and migrated from /b/ on 4chan to /mlp/. Upon seeing all the great fanart the community was coming up with I decided to try some of my own, and stand out from the rest by doing some pixel art (a medium I've been fascinated with for some time, but never took up actually producing) and that's also why I'm now here as well.
As for why I still like it; ponies are great! Especially Twily. There's a few other bronies here on Pixelation as well, notably Seiseki and Ai, I think they'd agree with me (though perhaps their "best pony" may be different)
