I think that suppression of knowledge isn't a good course

You really have to touch grass and actually listen to people who are experts in epistomology and medical science, they will have very contrary opinions to yours.

Focault did do some good showing some development of medical institutions, you yourself just think that stuff is neutral now and you also think that text book racism is "data" and "knowledge" which it isn't.

You also defend the "data" form a racist text book now and bound much more time than if you had stayed silent and instead read the links and sources in the thread which link to papers and articles challenging the racist ideas of "blacks no pain tolerace".
