Indeed, if we look at the past, there's a lot of ugliness.  Sexism, misogany, sexually assaultive behavior (watch the Trump/BillyBush video for explanation), racism, violence against homosexuals, discrimination against physically and mentally handicapped individuals, mistreatment of the elderly....we can all add to the list.  Putting in the "context of the time" simply means acknowledging that it was widespread, not that it was morally right...Surely, no one would claim lynching a black man for "looking at a white woman" was morally justified just because it was accepted during the Jim Crow Era.  Surely, no one would claim a boss coercing sexual favors from an employee was OK just because it was rather commonly done.  Surely, no one would claim belittling the mentally handicapped was OK just because it was done on nearly every playground in the country.  

Some of our "poster-community" use the term "politically correct" to trivialize concern with behaviors.  (cont)
