Let's be clear here.
No expert said milk was racist. None. That's a fabrication from a tabloid newspaper to get people worked up. That it's completely untrue doesn't seem to bother people very much, which frankly is what *I* see as the real problem.
Secondly, this is academic research. How are we to know things, without research? Lactose intolerance is actually interesting, there has to be some explanation as to why people of an East Asian descent are lactose intolerant, no? Now, to our normal lives, who cares? However, if you're an academic, it's a topic of interest. Why are we happy to bash those willing to do the work?
