So efforts to combat implicit bias are counterproductive because of... implicit bias? It's true that efforts to promote a diverse workforce have given many white men a mechanism to justify their racial prejudice, but that doesn't make those efforts futile. It just further proves there's a systematic problem we need to address.
When someone whines about "virtue signaling," it's because they can't fathom how someone can be more empathetic than them. It's a convenient fantasy dreamt up by stubborn conservatives. And if you "honestly believe" the only people that support equity & diversity recruitment practices are guilty white people, then you should actually talk to some people who aren't white. Diversity would help with that.
P.S. These aren't even quotas. They're aspirational goals a company sets when adopting more inclusive recruitment practices.
