Animals are tortured on "farms" all around the world for the sake of meat, dairy products, wool etc. It is just how people are. It is sick.
I have seen a little of the butchering animals are faced in farms (but not a lot), and while I haven't seen the videos or pics displayed by OP, I would bet they are substantially different. Animals are pretty much fed all their life, and then they are killed on the spot. Or even if they are young, like some chickens in a video I saw where they were instantly cut by metallic pointy wheels, death is almost instant (I want to believe). Physically torturing for fun and long periods of time, wouldn't compare that to a farm.
Once, a few thousand years ago, humans lived in the nature, with the nature, from the nature and they were happy. It makes me sick to think what humanity has turned this planet into and how animals are treated.
I bet some humans tortured animals at that time too, just like now, only that is a bigger scale cause of big scale economy.
If most people had the same mentality as hippies, not sure if you would be typing this in a computer with internet, having access to antibiotics, and what else.
The future needs hardworking people. You know, so that your grandchildren don't have to die cause Earth got finally over because of nature itself.
