The news does show the dead on occasion. They will usually have some warning as to the next clip being "graphic" but death is shown.
Each of us has something that affects us negatively or brings us to a bad head space. However, I do not think this complete avoidance or censorship of those things are inherently healthy to us as human beings. It is not how we handle the positive in life that makes us strong individuals but how we handle what negatively influences us that does. A sword does not become forged at room temperature. It has to withstand heat. Humans are pretty similar.
I understand you equate animal life to human life. Many people do, but a majority of the world does not. This is a fact of life. Unfortunately, you being in a minority position, shoulder much of the responsibility toward how you handle seeing these images. If the majority viewpoint changes on this issue you may be in luck as the tides will turn and censorship will occur because the action is condemned socially but I don't see that happening.
This is the difference between tolerance and acceptance. You have to tolerate this because people live their lives differently than you and with different values but you do not have to accept it.
It is no different than someone opposing gay marriage because they disagree with it on a personal level. They don't have to agree with it but since it is the law of the land, they do have to tolerate it.
It will be socially condemned within 100 years. I'm quite certain of that. It may be enforced in some places within 50.
I'm not just pulling that out of my ass - anyone who is paying attention to environmental science and the United Nations knows how easily vegetarianism could be enforced quite sooner than 50 years in some locations.
Cattle and hog farming are the second greatest environmental threat after fossil fuels. It's only a matter of time.
Because this is linked to human rights - due to global warming and global starvation - in a very real way, it's a no brainer, you don't have to be an extremist to embrace that logic in the context of a humane moral framework.
100 years ago women didn't have the right to vote, let alone race issues, and LGBT issues, and let's not forget gun control. If people imagine things can't change that rapidly - I actually predict this will be even more rapid, out of pragmatism and overpopulation, as well as a dying earth.
Human rights in the near future will be global, not national.
Great minds go back as far as Leonardo dI Vinci, Tolstoy and Einstein, and it's caught on more with average people who are paying attention.
There are scientists who argue that cultural obsession with meat, is nothing more than culture. Humans are physiologically similar to pigs, who can technically survive on garbage, but it isn't their optimal diet. Same with humans and meat - it's not only now unnecessary in most parts of the developed world, it's actually harmful.
