Without making a claim against veganism/vegetarianism, you do realize that people have been killing their own animals and eating them for many years. I'd wager most of the people who work in factory farms still eat meat. You don't find a huge proportion of butchers going vegetarian/vegan. I don't think that evidence supports that seeing how your food is killed has any impact on most adults, although it can be traumatic for children. The meet your meat campaign was largely ineffective, whereas making vegetarianism/veganism easy to do has shown actual upticks in vegetarianism that seem to be self fulfilling cycles. People aren't generally monsters, but that doesn't mean they want to sacrifice if they don't have to. Make a product that competes with meat on price, taste, and texture and I think most people will choose the vegetarian option unless there's significant social pressure not to.

Personally, I'm not directly against the small farmer nor the local butchery. But I'm shocked by what the big meat industry is doing. And I didn't have a clue until when I woke up recently.

The bigger problem is that eating meat, even if from small butchers, helps promoting meat consumption which, in turns, helps big industry continue making big money out of animal abuse and at the expense of everybody's natural environment.

Here you have what some former butchers have to say: https://www.youtube.com/watch?v=pDg7tlEJD64&t=4213

I slaughtered my own chicken when i was a kid cos i grew up partially in a village.

Typical Appeal to emotion nonsense

https://en.wikipedia.org/wiki/Appeal_to_emotion

"Appeal to emotion or argumentum ad passiones is a logical fallacy characterized by the manipulation of the recipient's emotions in order to win an argument, especially in the absence of factual evidence."

That you don't want to see it doesn't mean there is not factual evidence. Do you want evidence? Start caring about looking for it. You can start here [1].

And you repeat the same logical fallacy by linking that silly documentary HOPE
