Students write math contests - in USA and Canada. In both countries, most of the top scorers are Asian males. So what? Is there anything wrong with maths that discriminates against whites (or women)? No, white guys are kool and more interested in sports (than in geeky stuff)  than Asian guys are - it is their choice. There are more women statisticians than males (so women do do STEM if so they choose). There are more men engineers than women (maybe most girls don't care for fixing engines).  Do we need to have affirmative action in, say basketball and have 1/3 blacks, 1/3 whites and 1/3 Asians?  Do we need 50% of nurses to be males? Do we need 50% of truckers to be women?
The 19th and even a big chunk of 20th century needed affirmative action - now it has become silly.
