Although he might be annoying, I can't say I blame him.
After all, his goal was to get the best education he can, and he had no legal obligation to let society's goal of "righting the legacy left from slavery" or "establishing diversity" trump his own self interests.
However, I suspect that he only shares this aspect of his "secret to success" with select friends.
After all, such tactics are likely to make everyone (White, Black, Asian, etc) who would have loved to get into Harvard or another Ivy League school, angry at him out of a belief that "he" somehow took their spot.
Of course, similar tactics and opportunities exist for ambitious people in other fields. For example, there are lots of for-profit companies and consultants out there that will coach you and your firm on how to become eligible for the preferential treatment given to MWBE certified firms.
Needless to say, the best consultants know the fewest and/or cheapest number of changes that will result in certification. It's illogical to expect a firm to do more work than needed, right?
I am told one can respect the beliefs of others, without ratifying them.
