When you study undergraduate philosophy you aren't instantly bombarded with the current state-of-the-art in philosophical thought. On the contrary you spend a lot of time studying the musings of ancient philosophical ideas that have since been improved upon.

Should we stop teaching Aristotle and Plato now because many of their ideas have been vastly improved upon? Of course not, because teaching about those philosophers has pedagogical value.

Philosophy is much more about building and de-constructing rational arguments than it is about learning some particular set of facts from some particular philosopher. As such it doesn't matter whether western philosophy is "more correct" than non-western philosophy: it still offers arguments from different perspectives that can be used as a basis for practising philosophy.
