I realize this was three years ago. But it started with me posting an article in which male authors advocated that people should have more babies. You said
And I bet all these authors, even any not mentioned here, are all white guys?
and because the answer happens to be yes, you posited that they were instructing white people specifically to have more babies.
In any case, it sounds like we agree at this point. If a writer specifically urges white people to have more babies, it's probably racist (unless maybe s/he makes very clear that s/he's addressing white people specifically
only because they're the demographic that has fallen behind in birth rate). If s/he doesn't specify race at all, then the message itself, at least, is not racist.
So after much confusion, it looks like we can conclude the debate, don't you think?
