Hmm.. that hasn't been my experience at all.. but I'm sure there are some, I don't mind people butchering, as long as it's done humanley, but I sometimes am bothered a bit by the gross jokes.
Just have to ask, how many professional butchers and stunners do you know very well on a personal basis? Well enough to know how they work with live animals? I know several who are involved in rescue organizations and a few that are, paradoxically, married to vegetarians! There will always be the odd bad apple in any group, but overall I’ve found they are incredibly compassionate towards animals, and I have have known many quite well.
