The statist left have a real problem when trying to understand WHY a "one world without' borders cannot work out for humanity in general. The statist left with their adopted groupthink/hive mentality know that something is wrong with the border situation but once again another bogeyman shows up to block common sense in the form of identity politics, which leads to politician idolatry plus the dreaded "My Team" mentality which leads right back to where it all started, groupthink/hive mentality. The hapless statist left are travelling on a circular track & lack the ability to see that they are doing so. Add in the statist left's complete ignorance about the human condition(human nature) & they are like a spinning top that is spinning around @ great speed but going nowhere while spinning in place.
