Why is the evidence about homosexuality debated so strongly?
Vigorous debate and criticism is an essential part of science. All scientific knowledge is open to doubt, and every hypothesis is held only until it is supplanted by a better one. However, the issue of homosexuality is further complicated by moral, ethical, and theological disagreements about its status in human beings. Thus it is hardly surprising that evidence about its origins is questioned. Unfortunately, this means that empirical evidence can be used rather like biblical texts to argue that homosexuality is a normal variant on the spectrum of sexual orientation, a biological abnormality, a moral/immoral choice, or whatever else.
