She is clearly saying that these demographic changes are bad, meaning that America would be better off if it was more white. It would be hard to find a more textbook definition of racism.
I looked at the clip, and she said, "In some cases legal immigration". It seems primarily about low-skilled peoples coming over here. Everyone knows that immigrant groups don't necessarily meet the white benchmark on crime, education, etc generations down the line. Do you think Canada is being racist? They're taking in waaaay more of the cream of the crop as a proportion of their population than the US does.
