I think this is interesting because we have to ask ourselves: what is it that we're worried about? What do we imagine will happen when everybody thinks of themselves as being victimised? Some kind of cultural apocalypse? I doubt it. Our culture will be "weakened" in some ill-defined way and we'll be "beaten" or "taken over" by some other, more confident culture? I don't buy it.
Being a victim is not a purely objective matter. It is part subjective assessment and part social consensus. Social consensus actually determines most of how we react to it. I think at the moment the consensus is undergoing a major change and that feels uncomfortable for those who felt the balance was OK.
When the consensus stabilizes then people who claim victimhood that is without merit will be ignored. Sadly, some legitimate grievances will also be ignored. And the cycle will doubtless continue.
In the meantime probably the great majority of people will continue to NOT think of themselves as victims.
