I've butchered birds before and I've butchered deer before.
I'd butcher them live in my house if it was cheaper to buy them live. All my poultry is bought as the whole dead bird and cut on my countertop to save money.
I think they're talking about people who would never ever do it cause it's icky, but will eat meat. I don't think OP's expectation is that people would butcher their own meat in all circumstances
