I recently had to apologize to a vegetarian friend of mine after I unfortunately (again) displayed my ignorance. I told him that I didn’t think that eating chicken wings was any big deal, because those birds can’t fly so they really wouldn’t miss them. He got really mad after I told him that, because I was unaware that the chickens were no longer alive if the wings were removed. But he got even angrier when I told him that I didn’t believe that pigs were killed, because people ate “spare” ribs, suggesting to me that they were consuming an additional set that were just stockpiled somewhere and weren’t in use. (And I’m still not convinced that I’m wrong).
