Look, don't feel bad. Every brony out there has gone through pretty much the same thing. You don't even have to consider yourself a brony if you like the show. But we've all gone through that. I started off watching it thinking, "Okay, this isn't bad. But it's still just a show for girls." Then I found myself watching more and started wondering, "Why am I still watching this? It isn't that good..." And... well, now I'm a fan.
You don't have to tell everyone you meet that you like it, or be one of those crazy guys who buys all of the dolls or whatever. You can just like the show. But I'd recommend at least checking out some of the stuff that the community has made (music, art, games, etc). There's a ton of it, and a surprising amount of it is good. Plus, if you like fighting games, My Little Pony: Fighting is Magic looks awesome!
Also, if you feel the need to talk about episodes and whatnot, we now have a thread on VGC here.
As to why Blacksaber... he's a brony too.
