True - but I think there’s more to it than that. I genuinely think that most people (certainly most Australians) just like or admire horses: A lot of people ride them or have ridden them as kids, some people gamble on them, some people just love the muscles and power they exude, people like patting them and feeding them etc, people use their manure on their gardens, they pop up in fantasy fiction etc (unicorns and stuff), everyone seems to know someone who’s nickname is Horse etc, etc, etc. I think people just relate to them in a way - even people who aren’t that interested in animals generally still like them or appreciate them.
