Is 'Western Philosophy' just a misleading term for 'Philosophy'? You seem to have been deeply confused between racism and clarification. If one says, ok your idea is not philosophy, and you don't have philosophy as such, therefore you are inferior and you should not be sitting in the same train as us, or you have no right to vote, then this is racism.
But when one says, your idea is not philosophy, and historically your part of the world has never had a vocabulary describing Philosophy. But you can still use the word philosophy to whatever idea you feel it fits to be described as philosophy, if you want. It is up to you. But from my point of view, it is not Philosophy in strict sense. It is wrong, it is illusion and self deception on your part doing so. This is a clarification. That is not racism at all. It is just an opinion and argument.
This is a serious and typical problem when debating philosophical topics with non philosophical people. They somehow misinterpret the other party's argument, and then blow up into racism or sexism or whatever isms they want, and attack the other party personally and emotionally. I feel that it is also global effect of Internet SNS age, and should be avoided. Because it feels like that they are not into serious philosophical discussion as such, but are trying to accuse and punish others using the debates. It seems now global trend, that if you hate or disagree with someone, then just accuse him of racism, sexism or sexual harassment, and he will be taken off from the society next day. This is a serious crime itself, and should be stopped at all costs. Not good.
Well, Descartes, yes he is one of the most influencing classic Western Philosophers in history. I was not talking about a particular Western philosophy as such, but the Western Philosophical Tradition. It has had many different schools of different ideas and philosophical system in its history, so you cannot say this is What Western Philosophy is, in one sentence. But I have been talking about the evolutionary traditions which took place for 2500 years, and said this is what I think it is.
I will pick out ideas from Descartes, Hume or Kant, Hegel, Heidegger or Plato, where I agree with their points and methodology.
After all, one of the reasons we study and read History of Philosophy and the Classic Philosophers is that so we want to learn their ideas and systems, analyse, reject what we don't agree, accept what we agree, so that we could use the bits in moulding our own philosophy.
