"Hate to tell you, but the S and the M in STEM are Liberal Arts."
Are you being serious?
Math is not a liberal art by any stretch...in fact much of the appeal of a liberal arts degree is that it isn't difficult.
If you go to one of the service academies, regardless of what you major in, you always come out with a BS because you're forced to take advanced math classes in order to graduate.
And while you could argue that social sciences are definitely within the realm of liberal arts, they're soft sciences, and rarely are there any right or wrong answers.
