Meaning, a woman whose relationship with one group member threatens the cohesiveness of an otherwise all-male group.
OK, thanks. I "got it" that it was reference to Yoko Ono, but not what it actually meant!  

Wow, that seems like a huge stretch.
I'm not an advocate for big families by any means, but I think it's certainly possible to be one without racism being a factor. And vice versa.
I don't think it's a big stretch at all. While, unfortunately, I can't cite anything, I'm sure I've read about writers in the past--and maybe not so far in the past--writing openly that the white race needed to breed more to keep from being overwhelmed by the black, brown, and yellow "races." There is historical precedent for what I'm "hearing" as I read about these books.
But please note that I didn't say it was racist to have a large family of children. I said--or I was trying to say--that I believe there is racism buried below the skin of 
white authors who write books advocating that 
white people need to have lots more children than they're presently having. And if I were a betting man, I would bet next month's condo fee that the books discussed above are 
not aimed at Asians or African-Americans.
Of course, having 
no children, I'm no help at all. ...  
  
Quote from Milo: That's not racism, that's tribalism. There is a big difference.
Heh. If it walks like a duck and it quacks like a duck. ...
