Find the Logical Fallacy

This can be avoiding the issue or more commonly know as a diversion (tactic). Assuming this person is not a strict vegan, although not directly responsible for the death or abuse of sentient animals, the only rational responses are either something along the lines of providing justification or admitting no known justification. This would also be an appeal to false authority because people inside the industry are no more qualified to make philosophical or moral justifications than anyone else.

While we are addressing fallacies, I should point out that the question itself "Why is it justified to kill and abuse SENTIENT animals?" most likely commits the complex question fallacy . I think very few people would suggest that abuse is justified, and would reject the claim that killing for food is abuse.
