Why shouldn't one want the statement: 'women are better at maths than men on average' to be true?
The sentence you quote doesn't make a statement about whether one should want it to be true. It makes a statement about "wanting it to be true" being independent from 'being true".
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
