Obviously a line needs to be drawn, the question is where it is drawn. A good rule of thumb is that if it doesn't hurt anyone else and is between consenting people (adults?), you should be able to tolerate it. But you are right of course, some communities feel as strongly about killing animals for food as they do about killing humans. There are all sorts of edge cases involved in these situations. So I can't give you an ultimate answer to that - scholars have been trying to answer it for ages, and the only way to find out is to keep going with this muddled experiment that is modern civilization. :)
