Earlier quoted context omitted.
> people generally oppose [...] high-density, low-income housing. And there are good reasons for that. Are there, other than "I don't want to live near the poors" and "I don't want to see people who have problems"? That's not a good reason.
Quoted post unavailable.
There is no ethical framework in which "I don't want to live next to the poors" is an ethical sentiment - even though it is understandable in some ways. Well, maybe in Objectivism, or "Fuck You, Got Mine". Though even an Objectivist would be hard pressed to argue against someone else's right to build whatever they want on their own property.
