Actually, it is legal to discriminate on race, such as by saying that you only want to hire white actors to play Abraham Lincoln (BFOQ), and it is also legally murky to use things which can act as a proxy for race, and hence why police had to argue for the use of IQ tests to exclude high-IQ candidates. There are also parallels to BFOQ's in other peer nations.
