The Twitter account Libs of Tik Tok posted on its account this week what appears to be a lecture slide from a Purdue University pre-med course. The specific slide was titled “Racism is a Risk Factor for Stroke.” It details how black people have a higher risk for hypertension compared to white people up to 55 years of age.

The slide, which does not mention any other race, states that racism is a “disease” because it causes stress, which in turn causes strokes.
