Nobody has a problem with finding and researching group differences.
The problem is when you find them claiming they are genetic and innate while being completely blind to all the other things that can cause those differences. The bigger problem is when you go looking for differences specifically so you can "prove" the group is inferior. Usually inferior to the group you belong to.
It's like finding that null pointer and coming to the conclusion that the pointer is null due to nature and that's just the way it is. Nothing I can do about it.
