This has been a long journey for me, starting probably 8 years ago or so, learning about slaughter and honing my understanding along with my beliefs.
I would not eat horse myself and originally it was that disgust, combined with the inhumane treatment at plants that made me anti.
I've evolved since then to understanding that dictating what others eat is not my place. I get it. I eat beef and chicken and pork, and I'm not thrilled with how those animals are managed either and I do, outside of this horse forum obviously, advocate for better there too.
However, if the product is coming from the US I *do* believe we should make sure it's clean and humane. That's just how I feel about US products in general, we should lead w/high standards because they are possible to attain instead of lowering ours because others do so or don't care what's in it and because it's 'easier' or cheaper to accomplish.
Re; humane treatment and enforcement of violations in the plant and outside if they promised they would be better, the question becomes 'how many'... how many bolt misses are ok? How many horses killed or grievously injured in transit are ok? How much negative impact should a plant [or any business] have on the community it enters, and how amenable should they be to the wishes of the community around them?
I don't have any answers for these and the rest of those types of questions... So if I was elected Queen of the World, I don't really know what I would say re: the limits. That is in part because I do not believe they would do better or want to do better.
You know right before this horse labeled as beef thing I had a taco from Taco Bell, it was DELICIOUS!... then I had a burger from Wendy's that tasted just... not right... I HATE that this has ruined eating even fast food, for me. The drive thru will not see me anytime soon because seriously whether it's horse or cheap beef... they're probably equally bad for you and inhumane.
Cheap anything, seriously, is not something I am embracing right now. Good, healthy, quality, humane food costs.
Very early on, probably 11 years ago now, I heard an interview with Temple Grandin on NPR about chickens and the whole McDonalds thing re: their treatment, as well as her work with cattle. I thinks she's a very objective and clear thinking on it.
I grew up on a farm, my brother is still in Dairy. There are people out there doing things right.... it's when the corp. mentality jumps in that things go haywire, IMO.
