Pretty it up with ridiculous hats, booze and roses all you want—horse racing is animal cruelty. A pig with lipstick is still a pig. Nowhere else will you see people cheer while horses get whipped or shrug in apathy when a horse gets put down for underperforming. This isn't a sport. This is abuse. Here is PETA with more:
Horses begin training or are already racing when their skeletal systems are still growing and are unprepared to handle the pressures of competition racing on a hard track at high speeds. One study on injuries at racetracks concluded that one horse in every 22 races suffered an injury that prevented him or her from finishing a race, while another estimated that 3 thoroughbreds die every day in North America because of catastrophic injuries during races.
It's funny how people who have no idea what they're talking about love to judge something. Horse racing is not abuse. In fact, these horses get top-of-the-line medical care and are fed regularly. They are pampered and admired beyond belief! Here is Charlie Proctor of the Huffington Post UK with more:
I wouldn't mind being a racehorse myself if I'm honest! I would only work for 10 minutes with four weeks of rest and training. I would also get plenty of food, regular health checks, and a lot of attention as well as being treated like royalty. That is so cruel and evil, how will I console myself? Racehorses are treated far better than humans, especially if they are racing in the Grand National! Let's not forget what these horses are bred for, to run! They love to run!
