I do, in that our behaviors are cultural at their foundation. And we are CHOOSING to act this way. We like to pretend that the "other side" is "making" us, but that is simply dishonest and weak. We simply bind ourselves to our tribes, they defend and enable these behaviors, and that's that.
I recently read a piece that rings true to me: It has been so long since we behaved like decent adults, since we communicated and collaborated and innovated, that we have literally lost those skills. That they are like muscles, use it or lose it.
That's what I mean by "lacking skills", and yes, that's cultural, too.
