Watching this in a totally white audience was an experience. The little titters and nudges when 'make america great again' was mentioned, or about police officers shooting unarmed black people, or even one becoming president; to the we won mentality at the final phone call.
Then the deathly silence with the current footage being shown. I think quite a few people realised it's not just references.
These people still exist today.
They still have their rallies.
They still have their marches.
They still murder in uniform.
And they still hold these abhorrent views.

I think I even heard some people sniff away some tears right at the end once they saw the footage and heard the words of people who were there.

Enjoy the film; enjoy the jokes (it is a funny film) but make no doubt the characters shown still exist.
