"By analogy it would be like creating a social meme and scientific study of the negative pregnancy impact of malt liquor consumption (by urban black women), carefully ignoring the consumption of fruity margaritas (by suburban white women)"
If suburban white women consuming fruity margaritas were much more responsible with their drinking, so that they never consumed while pregnant, then we could study the effects of alcohol on pregnancy solely by focusing on the effects of malt liquor on pregnancy.
Crack use was widespread and used by poor pregnant women. Cocaine use has never been as widespread in suburban white populations. So researchers aren't being racist, they're investigating the problem where it actually exists.
