Sending 40 horses over a 6ft fence with a whip wielding rider on their back in a crowded arguably probably isn't a necessity. There are ways of having horses race that don't involve maximising opportunities to break their legs just as there are ways of rearing animals for food that don't involve persistent and systemic inhumane treatment.This is massive to the economy of the area and these horses well looked after don't see anyone moaning at other racecourses .. enjoy your joint of beef tomorrow...
Protests are about maximising visibility. None of those other events have a fraction of the exposure of the Grand National - In the words of it's proponents "the most famous steeplechase in the world". Quite a few of those protestors have no issue with horse racing as a sport - more the unnecessarily risky and brutal forms of the sport.I would guarantee you them protesters were wearing make up made from animal products, cotton clothing made from sheep’s wool, shoes and belts made from cow’s leather. They don’t give a toss about animals, why weren’t they protesting at Cheltenham last month or the Irish National last week or Crufts or any other animal led sporting events?
Plenty end up as PVA 'cos they don't run as well as the well looked after horses you mention. Horse breeding is a ruthless business with stallions often treated as sperm producing machines and mares being kept in a constant cycle of reproduction akin to the worst factory farms. Not being born is completely irrelevant...something or someone that has never existed isn't benefitting or suffering from it.The elephant in the room is that most of said horses, which are in the mainstay well (WELL) looked after, wouldn't be born if horse racing was removed.
Those alive would end up as PVA because keeping a horse is a costly business.
