controversial, sure, but its mostly people being upset that their cultural norms don't match the traits we observe in humans. we have already established that chromosomes do not determine gender, whether people accept it is a different question.
we're also nearing the point where the earth being a spheroid is controversial so I'm not sure controversy really has anything to do with how factual something is.
