I’m not gay, nor have I ever been discriminated against for something inherent to who I am as a person, so maybe I lack the perspective to even work it out hypothetically.

Either way, I agree with everyone pointing out that her inability to do her job without bias in this aspect definitely calls into question her ability to do it in the aspect of judging cases. And “calls into question” isn’t really harsh enough-- it’s proof positive that she can’t be unbiased in a job that requires it.
