Western philosophy is racist

So claims this article. And it is well supported by citations of western philosophers. E.g.:

"Kant himself was notoriously racist. He treated race as a scientific category (which it is not), correlated it with the ability for abstract thought, and – theorising on the destiny of races in lectures to students – arranged them in a hierarchical order:

1. ‘The race of the whites contains all talents and motives in itself.’

2. ‘The Hindus … have a strong degree of calm, and all look like philosophers. That notwithstanding, they are much inclined to anger and love. They thus are educable in the highest degree, but only to the arts and not to the sciences. They will never achieve abstract concepts. [Kant ranks the Chinese with East Indians, and claims that they are] static … for their history books show that they do not know more now than they have long known.’

3. ‘The race of Negroes … [is] full of affect and passion, very lively, chatty and vain. It can be educated, but only to the education of servants, ie, they can be trained.’

4. ‘The [Indigenous] American people are uneducable; for they lack affect and passion. They are not amorous, and so are not fertile. They speak hardly at all, … care for nothing and are lazy.’"
