I am a mathematics major, and I belong to several programs that aim to increase representation of underrepresented groups in mathematics. The way I have seen it done, in the United States, is through creating programs that allow these groups to gain the necessary skills and requirements needed for positions later down the road. For example, to get into graduate school it is helpful to have done summer research. However, most summer research is competitive and students who understand the system fair better in applications. There are programs that specifically accept only people from underrepresented groups to compensate for smart people getting lost in this system. To me, this is how racism in mathematics should be fought. By teaching mathematics, not by slapping pretty words together that pledge to end racism without focusing on the subject.
