This applies pretty much across the board for any information that doesn't easily assimilate into the "normal" value system. It is ignored. The condition people strive for is to have all of these questions settled, preferably by someone else and summarized in a convenient catch phrase that can be trotted out at the appropriate moment, proving that you do indeed have a "reasoned" opinion on the subject.
Most of the people I work with are racist in general not racist in particular and homophobic in general not homophobic in particular. Their experience simply does not include enough contact with groups significantly different from themselves to broaden their experience. They don't know so they use whatever label or category is conveniently provided for them. Usually by television. It would be a mistake to underestimate the grip this medium has on the world view of my peers. It is simply how most Americans learn about the rest of America.
