Oh great... e621 is jealous of the whole cub thing that happened over on FA so now they're one upping them with humans...
I think the op who thought human art should be allowed was right. Based on the fact we have a blacklisting system that allows users to chose what they want to (or not to) see and that I'm sure a great deal don't blacklist 'human -furry' or 'human friendship_is_magic' art because they like it... And finally, if there were a few of these images that were even deleted from the rule why bother with something so small?... And if there actually had been a decent number then that's a lot of content someone must have enjoyed and thus validated it being on the site.
As for what Princess Celestia said. I think a great way to cut back on the MLP would be by making it so you can't post those lazy MLP memes. Let's be honest, the bulk of the MLP stuff that needs to go is just a random screen cap with a meme stuck on... The humanized art is actually better as it provides real content rather than someone's lazy screenshot with a little text.
No matter how I look at it there just wasn't enough reason to put this rule in place. The only other explanations fall into ulterior motives and I'm not gonna even go into detail on them and will instead cut short with this. It's either trolling or an attempt to get the foot in the door for even worse rules that will have a devastating impact to the content on the site. For once I'm rather hoping it's trolling... Yep, a joke... That would be way better here. I mean really... This isn't 4chan, is it? Cause if it is I'm sure we can get some /b/tards up in here to start screaming furfag at all of us... ((Not a pretty image, is it?))
So yeah... I should apologize for saying all this, but in my defense I'm only looking at this from a purely objective stand point and systematically pointing out why the rule is kinda pointless. I don't know what is going on, but whatever it is it makes me worry about the future of the site. Sorry for being concerned about this place...
