I don't want to be merely dismissive of the modern fondness for the term - which is what everyone says when they are being merely dismissive. It seems to be mostly on the lips of younger people who believe they are not being heard, and even oppressed. I have no doubt it just feelz true to them. I note in passing that a primary symptom of Borderline Personality Disorder is the belief that "If you don't agree with me you must not really, really be listening to me." This can persist in the face of an amazing amount of obvious evidence to the contrary. They just can't see it.
Yet let me offer a serious counter to that thought. If you have not had some responsibility for the life of another person, you don't have any real lived experience. That other person might be a spouse, a parent, a parish, employees you care about, a school or ministry, or very especially a child, but without that you do not have a life shared with the long history of interconnected humanity. Weak ties with people who merely agree with you don't count. Emphatically don't count. Unless what happens to some other person (perhaps in extremes some other entity or cause, but I grant that grudgingly) affects you as deeply as what happens to you yourself, you haven't a clue. Let me pick an example conveniently: Are you a young high-status athlete or entertainer (especially male) who feels victimised because you 'n your friends can't just go and have a good time and don't get what you feel is proper respect from the police? Care for your aging parent, or a child, or a spouse with some real problem and get back to me later, wouldja? Because you have no lived experience until you have shared in humanity that way.
