So, she doesn't get to be in the public eye until Trig grows up? I challenge you to tell me ONE other public figure with a mentally challenged child, whose child gets ridiculed. And YES, there are some.
You talk like a victim. She gets to choose. She can either be in public and have her family be subjected to this stuff or she can go away and make it stop. She cannot be on the public stage making policy statements that make people mad (not me, but her opposition and their base), then play little miss offended every time someone tries to get to her.
