Why is racing picked out as so "cruel"? Is this JUST because it's in the public eye?
Horses suffer at the hands of humans all around the country, every single day.
How many little darlings attend riding schools where the ponies do 2/3+ lessons a day, the ponies are "saints" - they are pulled in the mouth, kicked in the ribs and have their backs bounced upon by untrained riders?
Cross country/eventing - how many horses are asked to jump enormous solid fences at great speed and fall and injure themselves every week all around the country?
Showjumping? How many horses are whipped and spurred and "forced" to jump huge fences? How many are pinned down with draw reins?
Dressage? How many horses are forced into unnatural carriage, trained in Rolkur, worked for hours a day in an arena. How many of these horses are never turned out in the field?!
Plenty more horses suffer at the hands of the novice owner, that can be found on almost every livery yard around the country, who doesn't have a clue what they're doing and end up laming/over feeding/under feeding/over rugging/under rugging and not fulfilling a horses basic needs.
If you're going to ban one, you need to ban them all. Anything else is downright hypocritical.
For what it's worth, I have had horses all of my life and I am pro-racing.
