What does "Come Get Your People" mean?

I had to Google that question as I struggled to understand the NYT op-ed, "White Women, Come Get Your People," by Alexis Grenell. The phrase "come get your people" does not appear in the text of the column, only in the headline. There's a subheadline, "They will defend their privilege to the death." I guess "They" is the white women, not "your people." Is coming and getting your people another way to say defending your privilege?

We see photographs of Susan Collins and Lisa Murkowski, so I guess they're in the set of white women Grenell is addressing. Is Grenell white? It feels creepy to Google to check someone's race, but she made race relevant. The headline makes it seem as though she is not white, because why would you address a group as if they were other than you if they were not?

I've read the column already, and I found it strange and off-putting, so I'm going to read it again to examine my reaction and I'll also see if the meaning of the headline pops into clarity and, if not, examine what turned up in my Google search of the phrase "Come Get Your People."

It begins with melodrama and careless imagery:
