It's probably just a memorized phrase -- the archetypal boogeyperson for the politically correct -- that author's fingers typed automatically, without thinking whether it actually makes sense in this context. Discrimination against women makes sense. Discrimination against non-whites makes sense. But how specifically is the interviewer supposed to find out the sexual orientation? Maybe indirectly, by asking about marital status (in countries without gay marriage), but is that even legal? Also, many straight while males are not married, especially the young ones.
