Yes I know every po dunk college up and down the country added CS to their collection (because all you need is a computer lab so it goes in with degrees like Math, Physics etc).

CS even at lesser colleges requires sustained discipline in the maths, sciences, logic theory, and much more depending on the university.

Liberal Arts is a very different animal and while it can also be a very rigorous program for committed students, it has a greater opportunity for students to slack off and still graduate. It is much harder to hide and get through a CS program with this mentality and so it deserves more respect than you are giving it.
