When a vegan is talking to a meat-eater about these issues, he or she is not “preaching”, “trying to convert”, or any such thing. We’re not telling you what to eat. We’re telling you what you’re eating.
Since animals can’t speak a language humans can understand (though I think the screams and terrified moans that fill slaughterhouses should be pretty much universal — all living beings want to live) it’s up to us to tell their stories and inform people of the suffering that goes on conveniently out of the public eye.
If, as a meat-eater, being exposed to this reality bothers you, it is not the fault of the vegan."
