It sounds like you care for this artist, it really does! But how do you know whether this person wants to be 'famous' on this website? I mean, sure, fame is good and all, but sticking to passion and digging deep down into underlying emotions using one's art skills is what an artist is truly about and is what all artists should strive for.

And what is a brony, exactly? It is only a name that a person who enjoys watching the show MLP:FiM can pick up at any time. It is entirely up to the person to label him/herself with this term to feel included with the larger mass of fans. In the end, it's just another label given by society to group up all of the fans of this show.

But in the end, if you're just trying to tell the artist that he should drop everything and stop liking the show, it's gonna take a bit more than 'they didn't put any effort in the animation'. This is your opinion, sir, and "between 7 and 12.4 million" people would beg to differ. And if you think all the animators do is drag and drop their characters into different settings, I dare you to take a visit to their workplaces and say that again once you're back. Good day to you, sir.
