Not totally true although I will grant many / most polo players probably aren’t really horse lovers - I would put Harry in that category definitely.
Certainly not denying that polo is very hard on horses but there are people in the sport who adore their ponies too.
I think I read somewhere that H&M have nothing to do with this project barring slapping their name on it - better chance it will be worth watching although I’m not sure their association will help it be successful.
