Reed’s philosophy department offers full one-semester courses on Aristotle, Hume, Wittgenstein, and Locke/Berkeley/Hume. Courses like this used to be a staple of philosophy departments, but there don’t seem to be any in Oberlin’s listings. In Reed’s philosophy course descriptions (http://www.reed.edu/philosophy/courses/index.html) you won’t find a single reference to race, gender, or feminism. In Oberlin’s, feminism is a topic even in the “Ancient Philosophy” course.
Larger schools can offer a greater variety of courses. At UChicago for example you can spend a term focusing on Aristotle’s Physics or books III and IV of Nietzche’s Thus Spoke Zarathustra. Williams offers similar courses (e.g. “Aristotle’s Metaphysics”), but many are marked “not offered this year”.
