There are many problems with WVS - the main among them is cross-national comparability. Thus comparing aggregated scores for different countries can be very misleading. But even if Islamic countries did score higher on the "democracy" measures, and lower on "sex" measures - the interpretation of these results that it is about Eros rather than Demos is wrong. Every nation has its favourite "sub-human species" - Southerners had Negros, Nazis had Jews, and Arabs have women. And it is not about sex, but also - or perhaps above all, about economic opportunity, education, abuse, etc. see http://unstats.un.org/unsd/demographic/ww2000/index.htm
Thus its wrong to say that Arabs are democracy-loving people, it is just their different sexual morality - because the oppressed groups are identified in their society by gender. It would be wrong to say that Nazi Germany or was a democracy, only their religious views were peculiar.
BTW, Huntington is a mouthpiece of the US establishment, and his views on social change border on mythology, but that does not mean that everything he says is groundless.
