From the stories that are told all too often, it is how they have to offer themselves up to the Hollywood power brokers to move ahead and then think they are expected to do the same to everyone else.
I have for a long time held the belief that actors become so immersed in being the person they are playing that after long enough they totally forget who they really are. So in essence, their whole life then is consumed with finding the easiest and most acceptable personality to make sure they stay in the clique so they can perpetuate the only existence they know.
It really comes down to towing the party line.
When one works in a world filled with X belief/philosophy, one adopts it or is outcast/unemployed.
Notice that every interest group is right there at the dawn of careers in Hollywood to ‘help’ them along.
My fave example is the Aussie group “The Veronicas”. Great music, great voices. Twin girls.
When they broke in America, PETA and the gay groups were their biggest ‘supporters.’ Suddenly, one went lezbo and they made all manner of PSA type ads for Gay/Animal Rights causes that helped them be ‘popular’ in the targeted demo. Lotsa marching in parades and “Supporting my gay sister” articles too.
Longoria is no different.
