I suppose its because the mainstream American definition of racism is different than mine, but I don't see anything explicitly racist in the statement. Wanting your own group to procreate and thrive doesn't necessarily mean you consider other races to be inferior or have prejudices against them.
What purpose do
you think specifying any group at all is supposed to serve, then? That the distinction is made in the first place is inherently racist and indicates assigning a higher value of importance to one group over the next.
