It is weird just how secretive the slaughterhouses are.
I don't usually discuss this sort of thing very much with carnists IRL, because I tend to find their "arguments" and their positions rather tired and boring and in general completely irrational. The "but where do you get your protein?" type of questions or "I tried being a vegan/vegetarian but it didn't agree with me because of my special DNA due to my ancestry of northern Europeans or whatever" conspiracy theories are especially fun. It's usually the carnists that go out of their way to be activists about their choices, not me.
I'll usually answer direct questions and leave it at that. I find there is a certain type of carnist that get especially defensive (almost always men suffering from toxic masculinity) around the very presence of veg*ns and want to get into arguments, especially while eating.
But there have been times where I've asked why slaughterhouses have so much secrecy in some of these "conversations" where the carnist just won't drop the topic and I've noticed that gives them some pause. At least for a small glimmer of time. I think it is because these carnist activists are the ones with the most amount of guilt and they know that most (normal) people don't want to witness what goes on in slaughterhouses...
I was raised in an agriculture focused community and did the whole FFA thing in highschool. I've since moved to another state and am now living the life of a city slicker, so maybe I've just become out of touch, but back then none of the "how the sausage is made" stuff was hidden from us. Hell we had a whole field trip to tour a pair of meat processing plants (one for poultry, one for beef).
Have things changed over the last 5-10 years? Is my experience just an outlier?
Not necessarily the slaughtering part, but the living conditions that these animals are stuck in, sometimes for years, is barbaric. Imagine being in a cage where you can’t walk and you have to stand in your own shit for days on end.
The ethics of animal slaughter and how it’s done are almost a separate conversation imo. No living creature deserves to be tortured (and outright torture does occur, see Earthlings or Dominion for the details)
people don't want to witness what goes on in slaughterhouses
That's exactly why they're secretive. It's also true of many other industries and processes. There are a lot of things we benefit from that have unpleasant origins. When it comes to meat, you can make a relatively easy choice about it.
In my country it's not a secret how these places operate, I went to a slaughter house as a class trip back in high school + one of our relatives owns a massive chicken and cow farm. The animals' conditions are vastly different here than what I see from these terrifying documentaries.
Oh, right. I didn't even mention how the tired old Dad "jokes" get very boring, very fast. Especially when repeated nearly every time, by the same set of people, at almost every meal. That, or they nearly reflexively have to talk about how much they love meat, love to hunt, love to fish, love to grill, yadda yadda. No one brought up vegn anything mind you, it's just the mere presence of any vegn(s) that seems to cause this....shrug.
