Some people just prefer to have a disconnect between their food and the animal it once was, because it's easier.
Story time. I currently cannot drive long distances due to some health issues. A few weeks ago, one of my Cornish X chicks from TSC died so I called and they offered to sell me 2 more chicks because I was outside of the window of replacement. Anyway, I had to ask my mom for a ride. She has given me more crap than anyone about raising meat birds. We were raised in the suburbs and taught to love and respect all animals, which is great, but I also think along with that there came an unacceptance of death (which is an unavoidable part of life that more recently I'm trying to come to terms with). She's always making comments such as, "How could you kill these sweet chickens after you raise them? How can you eat a chicken that you knew?" But I KID YOU NOT, on our way to get the new chicks, as she is still giving me a hard time about killing chickens, where does she take us for lunch?! CHICK-FIL-A FOR CHICKEN SANDWICHES!!!

I laughed inside as she told me what a bad person I was for raising meat birds, while we were in the drive thru line to eat meat from chickens that grew up in crowded, dirty conditions and never even saw sunlight, bugs, grass, or felt the breeze, and who even knows if they were slaughtered humanely.
I love my mom so I didn't say anything. But in that moment, I truly realized how people like the convenience of disconnecting their food from the life that it once was. You can't always change people's minds. But in those moments when I'm criticized, I just reassure people that I love and care for my chickens, and that they have a better life than any they have ever eaten (if they only eat factory farm food). They have a happy life, and a swift death. They see less suffering in their lives than most humans or other animals. If that's not enough for people, that's on them.
