The response from the political right has not been wholly negative. This debate shows you an interesting example of how even scientific quantitative sociology in the form of cross national comparisons struggles to be objective because when you are dealing with cross national comparisons, there are so many variables to choose from, one has to be selective and these selections are open to bias (in this case which countries to include and exlude. 15.
