I like the show and I like talking about it with other people who like the show as well. No it isn't perfect but I enjoy it all the same.
I don't blame this guy for quitting the Fandom the way he did. He was a public figure and he was bound to get questions about why he stopped making pony videos and I will never blame someone for being honest about why they are doing something. I enjoy the community and have had plenty of conversations about the show both positive and negative so I don't personally see the issues he is upset about as big problems, but obviously he did and I think we all just need to accept that and move on.
Focus on how you feel about the show and don't worry about what others think. If our pastel pony friends make you happy then that's all you need to worry about in regards to the show.
