Prop 16 would have repealed a current constitutional provision that made it unlawful for California's state and local governments to discriminate against or grant preferential treatment to people based on race, ethnicity, national origin or sex.

Yes, if you are a true Progressive, the defeat of this Proposition should worry you, but, I'll bet it doesn't, because you don't really understand what Progressive really is, just as you don't understand what Biden means by raising your taxes by repeal of the TaxCuts and Jobs Act of 2017.
