The legendary funny man was on a podcast this past week for the All Things Comedy network -- chatting with Steve Treviño and others ... and they were talking about George's legacy, especially as it pertains to paving the path for other Hispanic comedians.

Trevino said it was incumbent on the OGs of the biz -- like George -- to pass down the knowledge and assist up-and-comers in breaking through ... but GL disagreed on the way to go about that. He acknowledged he hadn't always been the most helpful, but noted he had shown the way ... arguing it was on others to chart their own path, the way he has.

Trevino pushed back, invoking Ralph Barbosa -- a young guy who's blowing up right now in standup -- and George almost immediately took issue with his name being mentioned.

George asked why Trevino was bringing RB up, suggesting he wasn't famous/worthy of getting roped into the convo. He then asked the room if it was messed up he was saying that ... but in the end, he stood his ground in writing Barbosa off as a relative nobody.

His takeaway point was ... look out for yourself. It would seem, in his mind, that means not talking about other comics or giving them a plug of any kind -- something Paul Rodriguez has alluded to when it comes to what he says is George's track record on this sort of thing.

A resurfaced clip of Paul telling a story about George is now making the rounds in the wake of this Barbosa snub ... and it paints an interesting picture. It would seem that even among George's contemporaries ... he's got a bad rep for not extending a helping hand to Latinos.

George would likely disagree with that characterization -- but he's also pretty clear in how he thinks he can best serve people, including Hispanics. A bootstrap approach, no doubt.

As for Ralph ... he's responded to all the chatter this has spawned, and a clip he reposted is quite telling. It's a scene from the movie 'Blood In, Blood Out' -- where Benjamin Bratt is getting grilled by his relative for turning his back on his own people.
