Dwyane Wade doesn't have a single issue with the way LeBron James publicly beefed with Stephen A. Smith last week ... in fact, he tells TMZ Sports he would have done the exact same thing if he were in the Lakers superstar's shoes.

Bron, of course, ignited the feud with the ESPN commentator while the two were at Crypto.com Arena for L.A.'s March 6 tilt with the Knicks ... after he had gotten upset over the way Stephen A. had previously spoken about Bronny James.
