For those of us old enough to remember when Gay people didn't even exist in media or for that matter in the world of the commonplace, reality changes slowly but it changes. Consider attitudes towards gays just a few years ago under Reagan and aids. Life is constructed in the head and the head gets its information from other heads, slowly heads change and what seemed odd seems normal and what seems wrong seems fine.
In the mid fifties, "generosity was voted the most conspicuous American characteristic, followed by friendliness, understanding, piety, love of freedom, and progressivism. The American faults listed were petty: shallowness, egotism, extravagance, preoccupation with money, and selfishness." William Manchester in "The Glory and the Dream" quoting George Gallup's Institute of public opinion.
I learned in School that the practice of identifying the race of a person arrested for a criminal act was limited to Blacks. Jim Smith, Black, of Cincinatti would lead the story and then the details would follow.
That practice no longer exists, but now, it is not at all unusual to see a story frame an evil doer's actions as racist or greedy and then identify the evil doer as Jim Smith, Republican of Cincinatti and so on.
The approach to bias is an evolving thing.
