> Why do people always think its the killing? Almost every vegan/vegetarian has most of their issues with how its raised and treated its whole life.

But definitionally a vegetarian is someone who abstain from eating meat period, regardless of the source. Someone can avoid eating unethically sourced meat but still eat ethically sourced meat and thus definitionally not be a vegetarian. So it's fair to assume that ethical vegetarians (those who practice it for ethical reasons) believe that all meat consumption is unethical. Otherwise they wouldn't be vegetarians.

I acknowledge there is probably a caveat of people who practice vegetarianism because they don't believe they can find ethically sourced meat and thus forgo meat consumption entirely. I find that strange though as cage free meat is pretty widely sold, at least in the USA per my experience.
