Have you noticed a cultural aversion to boundaries?  It seems the very concept of boundaries, and hence the concept of “others” has taken on a verboten quality.  A very disingenuous verboten quality I may add.
Certainly the phenomenon of parent as “friend” and child as equal member of the family has been observed and critiqued.  Do parents still even have locks on their bedroom door?  Whatever boundaries existing there are pretty much invisible to the naked eye.
But what of larger more far reaching lack of boundary phenomenon?  I recently was on the bewildering end of a religion conversation.  My conversational partner insisting that lots of Jewish people celebrate Christmas, and advising me that I was being dogmatic in my view of religion.  Isn’t that the whole point of religion?  Doesn’t a great deal of religious identity depend on identifying what it is not?  Judaism is a whole lot of things, and one of them is that it is NOT celebrating Christian holidays.  Do I know of many people of Jewish origin who in attempts at either not denying their cherubs or in their own ambiguous identity have embraced Christmas?  Absolutely.  But why is it wrong or “rigid” to maintain or at least recognize, a boundary?  Haven’t we fought wars over such things?  Don’t we have an entire government based upon parties whose very existence is predicated on not being a member of the “other” party?
We are all equal as human beings, but it is dismissive and offensive to maintain that we are all the same.
