I don't have a problem with horse slaughter itself - what I have a problem with is a) how the horses are treated while they are waiting to be transported to a slaughter facility, b) how the horses are transported, c) how they are treated at the facility itself, and d) how the actual act of slaughtering the animal is carried out.
Unfortunately, many of those are not up to par with my personal standards of how I feel horses should be treated to minimize fear, stress and pain.
I suppose I am on the fence. I would rather horses not be slaughtered at all than to suffer the way they so often do in slaughter houses...that being said, lack there of them would be devastating in itself, because horse overpopulation is a problem today. If I were to be fully against slaughter, however, my solution would be to decrease the population through means of education of breeding for quality horses, rather than mediocre and badly conformed horses, breeding with a purpose, not just because, and also following up with a good start and a good trainer to make for a horse who will at least retain if not gain value through his/her life, and also to promote euthanasia for older horses who have health problems, cannot be ridden and would be difficult to place in a home.
