Those kinds of poll results are fairly meaningless, because they don’t factor in the fact that most people don’t really know what DEI is. If you rephrase the question and ask ‘do you believe that merit should be the primary factor in hiring and promotion’ or ‘do you believe that a color-blind society under the law is a worthy social goal?’ or ‘do you believe that whiteness is a serious social problem?’ you will probably get results that tell a very different story. EVERYONE (basically) supports the concepts of diversity, equity, and inclusion… just like everyone believes that black lives matter. That doesn’t mean that most people support the weird and unscientific racialism of DEI trainings, or that they support tens of millions of dollars being embezzled to buy LA real estate, or that they support defunding the police. With questions like these the particular context is almost everything… the general public impression almost nothing.
