There are several unfortunate contradictions in this article, not the least of which is anytime you are including or excluding anyone based on factors they don't control (such as being a gay, aboriginal woman OR being a straight, white male) it is the very definition of discrimination.  I'm not sure why we would modify it with the word "reverse".  

If we're serious about eliminating discrimination in all forms, then we need to look at the multiple and complex root causes of the problem, rather than thinking that we've solved it with a simple "solution" like setting quotas.

The Prime Minister, for example, deserves credit for his gender-equal cabinet, but he has not solved the problem of gender inequity in politics.   There is much more work to be done.
