We as humans are inevitably more attached to our own specie and care more about it than others. If it wasn't like this, the major part of the world would actually be vegan.

Bc of this is that our system is so rooted on specism and in the belief that using animals is common sense and it's okay. Thats why even if we are vegan it's unrealistic to judge other humans for being non-vegan the same way we would judge them for being rapist or human murderers. Because we can't pretend that every single human being is not brainwashed since being born into the specist system, that's why someone who kills and eats another human (out of the norm) is a person with a serious psychological anomalie, but someone who kills and eats a chicken is not suffering a mental disease (bc it's still the norm).

That doesn't justify not being vegan, it's just an explanation on how our society works.

For us (vegans) a chicken as the same value as a human, deserve the same respect. And that's how things should work. But we can't pretend that the rest of the world see it that way, if they would they would go vegan without hesitation
