Couldn't agree more, I think the fandom forgets who the intended audience for the show is, Bronies are a happy coincidence.
There's enough grimdark nonsense floating around and, for me, MLP is like a haven from it all. It's sweet and innocent and cute and it should stay that way. It's the same with the shipping, I have my favourites of course, but it should be left to the fans, not shoehorned in for internet points.
