A kike "scientist" states the obvious....

"He told Earth & Sky that it’s the nature of ethnic groups to impose certain cultural behaviors not just on members of their own group, but on the region with which they associate their identity."

"And if there are no clear physical boundaries between themselves and other groups in the region, conflicts are inevitable."

"In other words, according to Bar-Yam’s model, the patterns of group behavior repeat regardless of continent or history.

The model shows that groups will avoid violence when physical boundaries are in place, or when the ethnic groups integrate with each other."

Gotta keep em seperated!
