It would appear, Mary, that you feel this negativity is undeserved by Ms. Hilton. Would you care to elaborate on your position?
Perhaps we're all secretly jealous of those in postions of influence (wealth, political power, etc.) who flaunt their position recklessly in front of the unwashed masses.
Is she manipulating the media to her gain? I would imagine so. Any publicity is good publicity when you are selling merchandise to teenagers I guess. I presume you could lump Tara, Lindsey Lohan, K-fed, and a few others in this category.
Perhaps what irks me is that the media (most likely because we, the audience, direct their attention through our patronidge) does not show any alltruistic or humanitarian goals sought by Ms. Hilton.
Contrast her publicized activities with those of Bono, the Pitt Family, the late Princess Diana, etc. and you begin to see why the general masses "love to hate" this person.
With great power comes great responsibility.
