It seems like you're faulting society's wish to increase diversity for lies about diversity. And, sure, that's true in the sense that being ask about the issue is necessary for an untruthful answer–but that's just a meaningless truism.
Large changes take time, and there are always setbacks on the way. The environmental movement created the concept of "greenwashing", which seems similar. But even that is progress of sorts, because it's literally "PR for environmentalism". When it's exposed, it promotes schemes such as certifications. And even when not exposed, it establishes good practices as the new norm for next generation.
