Damn bro, if you don't like ponies that's cool, you ain't gotta comment on it, because it sounds like you're trying to make me feel bad about what I draw, and THAT ain't cool. Don't spread hate buddy, because it can hurt someone's feelings.
And that's fine man, but you don't need to say that on pony art. Seeing as I just drew it, I obviously like ponies, yeah? And commenting on something and saying you don't like it for what it is is kind of a kick in the gut for an artist. If you don't like it, just ignore it, because a lot of people do actually like this kind of stuff. I'm not saying you're wrong for disliking it but you should really keep your dislike private with people who enjoy it.
