Around half of the US population has hypertension.
I'm guessing you wouldn't want your doctor just assuming you have it and start treating it though.
I have to disagree with a reply to this before me because I think this example doesn't do the comment about statistics mentioned above justice.
You don't want your doctor to treat you for hypertension, but you want him to check you for it to catch it early if you have it if you fall into a category that makes it more likely you have hypertension. This does not mean he should ignore the possibility of a disease in a non-high-risk group either.
Equally, black students being statistically speaking worse at math does not mean you should look at a black student and assume he is bad in math. But it can mean that funding for programs targeted at helping minority students going to math tutoring can be better justified.
I will not argue that based on statistics you should make assumptions about people, hell no. This is obviously racist. But assuming statistics (and being aware of them) are first and foremost racist would just be equally wrong.
The phrasings in the meme can be described as racist. But the structural problems that racism created and that lead to these assumptions cannot be fought by ignoring them.
