I can think of only one female acquaintance that is vehemently against it, citing the reduced sensitivity argument, but I doubt she ever had experience with a cut one (nor does she have a penis to know). As for men, I doubt it's the idea of being cut itself that makes them react violently, but rather the fear of undergoing surgery, in addition to the fact that uncut does the job for them: "if it's not broken, why fix it?".
Regarding the spontaneous survey, I think the group might have been just an outlier. 30% is pretty high with no cultural or religious background.
