Matthew McConaughey Talks Racial Injustice, 'White Allergies' with Emmanuel Acho

Matthew McConaughey's mission to do more to defeat racial injustice led him to an interesting chat with Emmanuel Acho ... where they broke down something referred to as "white allergies."

Matthew told the former NFL linebacker he recently learned of the term ... which he describes as white people's inherent prejudices -- ones they likely don't even realize -- based on their upbringing or history.

The actor suggests these "white allergies" apply to all white people -- even someone like him, who grew up in a diverse setting and has had black friends his whole life. He gives a prime example of one of these allergies too ... and says it SHOULD have been obvious to him.

Matty's eye-opening chat went down on Emmanuel's Instagram talk show, "Uncomfortable Conversations with a Black Man."

BTW, Emmanuel said he's personally been exposed to a lot of "white allergies" -- he listed them off, and explained why they're really racist microaggressions in disguise.
