I don't know why Mom's get why the movie is horrible in many ways that can describe it. Firstly, they don't know the internet fandom that we are in right now, the bronies and the pega-sisters. I think if more and more Mom's get attention of this serieno about bronies and pega-sisters, Common Sense Media will come and stop the brony fandom once and for all. The Mom's should know that we have the power to like and try things out, not the way that male people watch this movie.
Its just a movie, not the end of the world. :/
