Vegans often say that people eat meat because they don't see the cruelty that animals are put through not realizing that the reason that they can even use this as a rhetorical point is because people have been sensitized to cruelty towards animals precisely because they can't see it.

That said I don't find their position entirely unreasonable and in the long run I see things going their way as we distance ourselves

To your point of farm animals existing only because we bred them I have heard vegetarians say that it would be better if farm animals did not exist.

On another note, I don't believe that anime should be even used to tell stories like this which can be easily told through live action.
