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.
