Diversity is advertised too much those days, but in reality, it barely matters.
The advocates need to further explain why it is good for the team and such. Since many companies, including my own, implementing the diversity initiative by lowering the bar for the diversity candidates, even those that are being turned down at earliest stage, still interestingly, being rescued later. However, even people take issues about the candidate in question, they are afraid to voice any opinions, because the fear of being labeled as bigots. As ironic as it gets, during the group meeting, that the said candidate apparently doesn't have any deliverable for 6 months, still being praised with great efforts and hard works, while others in the team are pressured to take over what is supposedly to be done by the candidate.
I don't think this put the diversity initiative into good lights. It only further convinces people that it is more to the vanity of higher management other than productivity/benefits of the team/company itself.
