12:20 PM PST-- Wayne seemingly just addressed the interview on Twitter, saying, "Is intelligence always misunderstood?"

Lil Wayne couldn't care less about the Black Lives Matter movement -- like, at all ... 'cause it apparently has nothin' to do with him ... according to Weezy himself before he stormed out of the interview.

Wayne was on 'Nightline' Tuesday and he made no bones about it ... NO f**** given when it comes to BLM.
