"Carnism" that's the difference between vegans and non-vegans.
Only vegans view their diet as a lifestyle and shit on everyone else who isn't vegan. We're not "carnists" we don't give a fuck really except that we hate vegans. Why? Because you lot are the pushiest, most openly judgemental, arrogant pieces of shit to walk the earth.
Carnism is simply a name of the belief system. For a long time it didn’t have a name, which is something that psychologically helps oppressors not question their own actions.
So it was given a name to help point out that it is, in fact, a belief system. The belief that eating animals and their secretions is normal, natural, and necessary.
Except we lack a belief. You're the ones who believe something. We simply do not believe your belief system. It's like trying to call atheism a religion, it's not.
