Yes.
To properly answer the question, we have to go back to one of the core ideas behind MLP:FiM:
"Girly" or "feminine" does not have to mean "stupid", "bad", or "inferior".
Right now, if a girl wants to enjoy masculine things, she's generally seen as a tomboy. However, if a boy wants to enjoy feminine things, he's looked down upon, seen as weak, and often called "gay". Some people have even called us mentally ill for enjoying something that we're "not suposed to". Lauren Faust (the show's executive producer) herself has said on DA that girly things are regarded with so much contempt. There's this mindset that if something is targeted at girls, it's going to be shallow, condescending, and not very interesting. MLP:FiM challenged that mindset head-on.
I think the main hook that kept people interested was that they were surprised by just how good it was, despite being based on one of the girliest franchises on the planet. Here was this show, targeted at little girls, and it had interesting, likeable characters, good writing, a good sense of humour, and even world-building. The idea that something made specifically for girls could have a wider appeal was actually a foreign concept to us. So then came the realization that just because something is girly, it isn't necessarily bad.
We were all scared at first. "Oh God, what is happening to us?". But we stopped, and took a look at ourselves. Liking this show hadn't turned us gay. Our penises were still attached. We could still drive stick. Those of us who were in the military hadn't lost all of their training. We didn't suddenly lose our ability to do and enjoy "boy stuff". We could still be as masculine as ever. We just also enjoyed this one feminine thing. Which lead to the second realization, which I'll let Paarthurnax explain:
"What is better Dovahkiin? To preserve one's masculinity by eliminating one's femininity, or to have one's masculinity endure and coexist with one's femininity?"
There are reasons why we try to get other people to watch the show. We aren't out to actively annoy people. We just think that, for a number of reasons, this show is worth sharing. The biggest reason is that we enjoy it, and that's what people do when they enjoy things: they share them with others. I also think that, whether we realize it or not, watching the show has altered our perception of gender values. So, maybe on a subconscious level, we want to share our realization with others. However, as 4chan, Fox News and others have shown us, this is an idea that a lot of people aren't ready to embrace.
And all this is an unintended byproduct of us enjoying pretty ponies making friends and going on adventures.
