That tendency to react to other people's opinions and to be easily offended is a behaviour that is most prominent in the Anglo-Saxon world (and North America in particular) where defense groups and lobbies are powerful. I'm not commenting on whether or not that kind of policing is actually good or not, just that this is not "everyone", just "Some people in the Anglo-Saxon world, especially the United States".

EDIT: I live in France and I have never observed that kind of behaviour in the Latin world or Eastern Europe for example. Most of the time when someone would say something "offensive" that doesn't directly impact the people in the room, the reaction goes along the lines of "Well, that's your opinion, whatever" or some form of polite debate.
