this episode Applejack is being rude to some fashion ponys and when rarity confronts her she says "its just my HonESt opinion" it honestly reminds me of homophobia. so rarity takes her to meet someone who hates apples and Applejack realizes that her opinion was hurtful and that her opinions shouldn't hurt her friends or others. honestly maybe it was about homophobia or racism. MLP does have LGBTQ charters, Applejack (lesbian?) rainbow dash (lesbian?) sunset shimmer (bi) bonbon and lyra (cannon lesbian couple that got married on screen) scootaloo's aunts (they're a married lesbian couple) so maybe it was a bit about it idk
