Did you see me say anything about the dog being fed a vegetarian diet? No. I was simply giving advice on how you might convince more people to adjust their eating habits in a better way with the added benefit of explaining why your current manner of arguing for it is flawed. That appeal to emotion argument works for some, but not a lot, of people. If that's somehow "evil" then feel free to ignore everything I've said.

As for 16 year olds visiting things like that, i honestly agree. That's around the age where you should be shown some uncomfortable stuff, and allow them to come to their own conclusions for these topics. It may work to help lower meat consumption, it may also do almost nothing at all. I've seen it myself, and while it's not, lets say ideal for the animal, it is efficient and for the amount we eat as a society, that efficiency is kind of required.

If we ate less, I'm not even arguing for none either necessarily, we could significantly lower the need for industrialized animal farming like that. It would have a ton of benefits.
