I really don't see the big deal. It's totally possible. There are several genetic differences between ethnicities, I don't see why one of the differences can't cause one group to grow hair faster than another.
I don't think they're saying that every single black person has a slower growth rate than other races. But according to their results, it's just a trend they've seen ... in general, black people's hair appears to grow slower.
It's just like with the whole atheletics thing. The kenyans always seem to take out the long distance races. And black people tend to be the better sprinters - genetically, it is said we have more fast twitch fibres which help with sprinting. So it gives us some sort of advantage. But that doesn't mean every black person is a great sprinter. It just creates a general, observable trend.
I really don't knw why people are getting offended. So what if our hair grows slower???
