The real Black Panthers? They would... probably still prefer it to be a sister org to focus on the African American community but they would very much be allies.

These Black Panthers? Who the hell knows?

Because the thing people forget is that the reason The Black Panthers were so effective wasn't because they were walking around locked and loaded. It was because of all the community outreach they did. So when the (white) cops and government came knocking? The neighborhoods locked arms because these were people who had been protecting them and who cared about them.
