I think that was more of a sarcastic comment regarding how far some people go with things that just aren't true. For instance, I overheard a heated discussion on a plane not too long ago. One individual was claiming that the other not eating cajun food was rude and racist. Yes, racist. Now, any person with common sense *should* know that not liking a certain ethnic food does not make you a racist.
I see the biggest problem in a lot of these politically correct situations, is that people, who are not even the supposed "victim" of the alleged discrimination, are the ones to yell "OFFENSIVE". So many people are inclined to be offended because something *may* be offensive to someone else. (i.e. A group of white people may demand a road name be changed because it is "offensive" to, say, Native Americans, yet the Native Americans don't really care). Of course, I'm not blanketing everything as though this is the case, but if you look close to the more "ridiculous" claims, you'll more than not see that it isn't even the alleged victim yelling the battle cry.
So, long drawn out novel later (sorry
), I believe his comment was saying more so that, no, a lion eating a zebra is *not* offensive to vegetarians, because that's ridiculous, but I'm sure there is someone out there (who most likely isnt even a vegetarian) would be daft enough to yell "offensive" because they are afraid it *might* be offensive to someone. And sadly, those are the people who yell loudest and longest, and usually are the culprit in the nonsensical changes that are made. And another problem with those people, is that they drown out the people who have truly legitimate claims of wrongdoing, which makes it hard for anybody to sort out the truth amidst the crazies.
