No, the reason its an issue is that people's emotions are tied up in their opinions of their own species. They want to believe cetain things about humans, and when science shows them that reality is different from their beliefs, some people take it very badly and refuse to accept reality. A good example of this is the "controversy" over evolution v. creationism; there's no real controversy, of course, but some people just refuse to accept the reality of evolution so they've created a whole ideology of evolution denial to boost their flagging self esteem. (I suspect that at some deep hidden level, evolution deniers do accept it).
