I absolutely love this show. I'm a teenager now but I watched this in the early 2010s and really enjoyed it - looking back (I recently rewatched it), it's actually objectively an amazing tv series. It teaches about stereotypes and prejudice and the importance of being true to yourself and presents it all in ways that young children can understand. An episode that I particularly remember and like is one where a new girl joins the stables, I can't remember her name but I know she was from an indigenous tribe. Basically, the riders are assigned to do a culture parade and they have to come up with a culture to use - the two stereotypical mean girls, Chloe and Zoe, decide to dress up as "native Americans" and say their outfits make them look like Pocahontas. The new girl is, rightly, incredibly offended by this, and runs away. The rest of the episode is spent explaining that each indigenous tribe has its own unique culture, showcasing traditions that the new girl follows and having the rest of the riders learn more about what it means to respect others. In the end, they do a "melting pot" parade, where each rider comes as their own country/ethnicity and waves their flag. It has a very diverse cast and touches on romance, xenophobia, jealousy, vanity, rumours and so much more. 100000% recommend - I think watching shows like this shaped us far better than the shows of today will shape children.
