It is a problem of grammar and language! As others here have said, no one is claiming that the notion of math itself is racist, but that math education can be. The 'agenda' seems to be to make sure that marginalized groups are better able to learn math. Do you disagree?

As for the 'highly valued' bit; one could argue that mathematics built for problem solving creative issues (including in computer programming) is now valued more than it was then. That could lead to different curriculum than before.
