Agreed. The subcultures started this trend in the sixties and now they are accelerating this trend since any subculture can mimic the sense of a shared culture with the closed circles of internet media/social networks. We're building filter bubbles ourselves, having less and less time for understanding, leading to suspicion and in the end conflict with subcultures perceived as threat to our way of living.
