Oh dear oh dear, well done 'farview', for opening up a Niagara of ill-informed guff!
The folk criticising racing are doubtless doing so because they mean well, but a bit of research would help them.
The critics ALL seem to be labouring under the severe misconception that young, soon-to-be racehorses are out in fields, all waiting to be selected to go racing. In fact, worldwide, many tens of thousands of horses are SPECIFICALLY bred for racing, and without the sport (which it is), they would HAVE NO LIFE AT ALL.
In that racing life, contrary to the "cruelty" misnomer, they do indeed (as some have reported) live a generally pampered life, and they don't usually race that often. All those of us at an advanced age will take far longer to get a GP appointment than the time most racehorses have to wait to get a vet attending them!
And yes Gilly, there are some casualties, some sadly early deaths, but it's NOT "many", it's a tiny minority - unless you have a very odd way to quantify "many"?
IF folk on here are criticising, I'll ask them if they eat meat, any eggs, chicken, pork, beef or lamb crossed your lips lately? If so, that marks you as a hypocrite, as THEIR early death rate is just about 100%, nothing like what it is for racehorses. And for quite a chunk of them, their living conditions are far worse, but campaigning re battery chickens or veal isn't as easy as attacking racing?
Oh, another couple of points, 1) horse-racing is comfortably in the top 10 of employers, if you include all the ancillary businesses. It won't be banned, but if it was, the effects would be catastrophic. And 2) the comment equating racing to fox-hunting shows the level of mental fragility involved. The best research ever done (Bristol Uni) noted that hunting is irrelevant in controlling fox numbers, and therefore it is a sad pastime for sad people seeking a bit of a social upgrade (or whatever they think it's for). Wilde was quite correct. And horses being ridden across fields chasing the 'hunt' are more likely to get injured than racehorses.
I do hope that helps, and if it hasn't, go back and re-read that "no life at all without racing" point? AND -- it's a sad irony that folk like Blue-belle will continue as blinkered on this as some of the racehorses in question?
