Not sure what you’re asking for my feelings on. That said, there are certainly a lot of pro-legacy, anti-affirmative action folks.
I am not pro-legacy, but I am against governments trying to ban it (I know CA technically did not ban it they just stripped funds from schools that do it, but close enough for me). I don’t find what’s happening with Affirmative Action and Legacy to be tied to one another in a meaningful way, or at least not in one that makes logical sense to me from any moral, fairness or equality standpoint anyway. My strongest feeling I guess is that both should be permissible in private schools, but I would not be worked up if an individual school decided to keep or jettison either based on its interests and what the public is demanding.
