Who are the real insiders?

 We have discussed the chareidi chiloni divide the Ashkenaz Sephardi split FFB vs Bal tshuva, young vs old, American vs Israeli, Litvaks vs Chasidim as well as Orthodox vs non Orthodox. The real question is who thinks they belong and are not only see themselves as insiders but the transmitters of the true mesorah

I was told the only people who feel that they truly belong are the grandchildren of gedolim - everyone else feels like an outsider.
