From your paper (which studies data from 1999 forward in Europe, not the US), analysis of the data indicates (p 12) "For Western Europe, the effects of level-1 predictors are largely in accordance with the usual findings in studies of prejudice in general. The odds of expressing anti-Muslim prejudice [...] increase by around 12% for each additional decade of age." in Eastern Europe the pattern was weaker, but still statistically significant around age.
There is no analysis of the reason for this, so I'm not sure of the prevailing theories, but it seems to support my theory that part of the disparity between Ms Moon's attitudes and those of the rest of the commenters could be linked to her age, and it seems not illogical to posit a connection between that and the historical perception and events of a generation or more ago.
You are aware that when the PLO first formed in the late 1960s, the US was a major target of terrorism as a strong ally to Israel? Muslims were not a large immigrant population here at the time (compared to now), so the predominant generalizations in the news etc were of violent foreigners who wanted to kill us and destroy our country, including the 1985 incident Moon mentioned where the Jewish guy in a wheelchair was murdered and tossed off the boat
. You can see that characterization in a number of films also, for instance.
(This is ignoring the domestic trend that was also present of black activists converting to Islam, following after Malcolm X. Not sure how much that was reported at the time.)
Since Europeans were not targeted by Islamic terrorism the way Americans were, I doubt that the generalization of this paper's results to the US is a scientifically valid leap of logic.
The prejudice toward Muslims who are our neighbors is definitely both increasing and ugly right now, and I don't disagree with either of those statements. But as reported by her, Moon's prejudices have much longer roots than just recent events.
