It's probably both groups, asians and poor and middle class whites. If the winning narrative is racial diversity by proportion of population, you now find yourself largely in competition with people of your own race for one of the coveted spots, which means that the smart tactic is to find a way to exclude a subset of your own racial group that you're not part of so you have less competition. Liberals making conservatives personas non-grata means they have half as many people to compete with for a coveted spot at the top of the pyramid of power.
