All of the people I know that had contact with farm animals are the least moved by PETA-like farm cruelty videos. They often shrug and say, "in my farm it's not like that".

On the other hand all of them are against seeing dolphin or whale cruelty even if only a handful of them ever saw any of cetacean (me included).

I know that this is all anecdotal evidence but it the most that I can produce.
