Let's get it out of the bag here – I am a 32 year old GUY, and I LOVE this show. And I am not alone with this… Which just goes to show how well-written, clever, funny, and also cute and entertaining this series is!
The author of this article obviously never even watched a single episode, to make so many incredibly wrong assumptions just from glancing at Hasbro's official site and the few seconds long intro.
Firstly, there are no "black" ponies or "white ponies". The author would know this if she knew the previous MLP shows… There are no skin color difference races amongst ponies. There are three races – 'earth ponies' (normal horses), pegasi, and unicorns. And, 'lo and behold, there are two of each race amongst the six main characters! You cannot get any more equal then that.
As to why Princess Celestia is white? Well, "maybe" because (again, had she watched the show the author would know), she is not just a ruler, but also the representation of the Sun, who controls the day, while her dark blue sister, Princess Luna controlled the night. Yin and Yang, both are needed.
Rainbow Dash is not a lesbian, again if she'd watch the show, she could tell this. She is kind of a tomboy, but it'd be pretty racist to assume every tomboy is a lesbian. I had known a girl who played soccer with us boys in school, in fact everyone wanted her to be on the team, and she beat up boys older then her… yet now, she is married to a guy and is a mother.
Twilight Sparkle is sent to Ponyville not to stop her studies, but to also study the "Magic of friendship" (as the title goes) – and throughout the series so far, she remains a thoughtfull and level-headed, somewhat bookish pony, who nonetheless realized she was missing some good friends from her life.
Overall, I think the show is a morally excellent guidance for kids. Episode 9. for example, teaches us that just because someone is odd and outlandish and different, we should not judge or shun her, when the ponies discover that the odd zebra girl they think is a witch who cursed them, actually warned them of the danger and is working on a cure for them. Or episode 8., which has the morale that even if you don't like someone at first impression, you can try to find some common ground, especially if you and her have a common friend.
I'm writing this because I like this show, and I want to put a stop to any actions Hasbro would take based on this biased and very unprofessionally written review. As they'd say in Equestria, "What the hay", if you want to judge a movie or cartoon, at least watch it first. On December 9., at least 7 episodes were already uploaded to Hasbro's Hubworld Website… So Ms. Richter doesn't have this excuse either.
