[I]t shall be unlawful. . . [t]o refuse to sell or rent after the making of a bona fide offer, or to refuse to negotiate for the sale or rental of, or otherwise make unavailable or deny, a dwelling to any person because of race, color, religion, sex, familial status, or national origin.
这句话和Title VII或ADEA的disparate impact条款显然不完全一样——它没有effect、affect之类的直接和“效果”相关的字眼。但是“otherwise make unavailable”是什么意思呢?是聚焦在行为(make)上?还是结果(unavailable)上?
