Get rid of Tribalism?
The plan has been to create as much tribalism as possible. Divide and conquer! The Kenyan and his two terms in office (now third) have made that very clear to anyone not in a drug induced stupor.
Not just create tribalism, but to import as many anti-Western culture tribal members as possible.
How can you determine when the left adopted tribalism? Look for when the media last described the US as a “melting pot” and spoke of immigrants assimilating into US culture as a good thing.
As with most leftist dreams of unicorns flying between faerie castles in the clouds, multiculturalism is foolish and destructive.
