Agreed. I think, however, that addressing "white men" as a group misses the specific target of criticism. The 23 year old entry-level "SWE-I" - who happens to be a white male - is not the 'king' and not a threat to anybody. Lumping him in with men of great power, wealth, and influence because of his race / sex / cultural background is problematic. It's more likely to alienate him and lose him as a potential ally, than to get him on board.
On the other hand, informing VCs or other gatekeepers about the desire for diversity in the profession, and holding the thought leaders to a high standard, does make sense.
