Real Men Eat Plants, but Reporter Sticks to the Meat

There was a great story on NPR this afternoon about vegans and masculinity. There was just one small detail that rubbed me wrong. When is it OK for a news reporter to make announcements about him or herself while reporting on a topic? In this case, maybe to prove her credibility, Neda Ulaby needed to clarify that she eats meat. If she were reporting on serial killers, would she state she abstained from murdering people? If she reported on the World Cup, would she make a point that she prefers American football? This is not only inappropriate, but it is irrelevant, as well.
