There's been plenty of mainstream coverage recently about the ugly stuff that goes on in horse racing and associated industries. This is as good as any place to look into it. There have for a long time been more comprehensive treatments like this but until it hits the telly no-one wants to believe it. (Both those links are from organisations that aren't driven by animal rights at all).
Imagine: Millionaires buy a horse, get trophies for their performance, then when the horse can't live up to their ever exceeding expectations they are popped off for a bullet, or whatever undignified death is cheapest. Break a leg? Get a bullet. Lose a few races race? Get a bullet. Millionaires - like our fave Gerry Harvey - that could easily sustain hundreds of horses if they saw them as anything but commodities and investments.
And that's aside from the fact that these horses are being bred purely to satisfy our whims for entertainment and are pushed hard their whole lives.
There are so many better things to get dressed up and pissed for on a Tuesday. Why would you partake in anything this vile industry offers?
So much unhelpful from both sides of the coin on here really. This stupid left vs right thing is just manufactured division (by both sides) to keep everyone distracted from their shared problems.
