I did not read all the responses but wanted to add my thought on this issue.
I think if more people were pro- slaughter, the slaughter houses could be more humane. I think the real problem is not if you should be pro or anti slaughter, because to me slaughter is ,sadly,necessary but the problem is how to make the facilities better to accommodate horse slaughter. If we make the killing process more humane them most people would, intelligibly, be more inclined to accept slaughter.Imo.
So as of right now, I don't think I am completely decided.
Chocolate is the answer. Who cares what the question is.
