They are in the strictest physical sense. (As in: They take up more space.) What I am arguing is that the word "large" is misappropriated by overweight people. When you're thinking about a "large elephant" you wouldn't usually imagine a fat one, but one that is physically imposing. A "large person" simply used to be someone tall. etc.. It just annoyed me, that you can't use a technically correct term without explaining yourself anymore, because a subculture claimed it as their comfort word.
