I'm going to be 100 with you.
I watched the first 3 seasons of the show, not because I was necessarily interested in the show, but because I love cartoons, animations, and art. I liked the fist two seasons, hated the third, and didn't look back at the show until I saw on the internet that there was another dragon episode so I went to watch it.
But that is not what you asked is it, am I a brony? No, why? Multiple reasons really. One, I hate labels, once you accept a label onto yourself, you get attached to you all the negative stigma that comes with that label and brony has a shit load of negative stigma. Two I find the word quite ironic since among "bronies" I have heard this type of arguments, "Some guys won't watch/like the show because of masculinity" or something along those lines it has been a while since I dealt with that community. I find it ironic that a group that supposedly firm or comfortable in their masculinity needed to have a noun for their gender, "bro" in the name of their fanbase.
Three, after the first episode I really only cared about Spike, for obvious reasons or reason I would assume are a little obvious at this point. Also, I fucking hate Fluttershy, come at be bronies! Ok I did like Rarity a little, but that was mostly for the connection with spike.
