While the author's intentions may be noble, it has been long established that two wrongs don't make a right.

He is, in fact, advocating for discrimination against 'white, straight males' and without a defined end point.  What exactly has a 20-something young man, raised in an egalitarian generation and era, done to warrant such punishment, other than being born white and likely straight? He did not commit the sins of generations prior -- why should he do unlimited penance for them?  Is it not wrong to discriminate against someone based on the colour of their skin, regardless of the reasons?

Moreover, it completely ignores the overall demographic shift and the fact that it takes many years, if not decades for a cohort to work its way through a system, and ultimately the trend is more important in determining what, if any action should be taken.

Encourage 'non-traditional' candidates to engage?.  Absolutely.

Perpetrate discrimination against a declining demographic? Absolutely not.
