I think the point being made is that it's the major, not the broad school classification, that should be the focus. For example, MIT offers a major in Literature and many other so-called "Liberal Arts" majors. Many so-called Liberal Arts schools offer majors focused on Pre-Med.
One that always throws me off is Northwestern. It's generally labeled a "Liberal Arts" school with world-wide recognized programs in performing arts, journalism, business, etc. Yet they also offer a solid engineering curriculum.
