something terrible happened to Ivanka or Don Jr. It's a good theory and worth thinking about. I think about Trump's father and how he would have reacted if something happened to Donald Trump. I think he would have been devastated, but not like a normal father. Fred would have been devastated because he created Donald Trump in his own image and Donald became an extension of himself and an exteriorization of his idea of his own success. "I taught him how to do this. He is successful because of me."
This is a family where the males don't observe or respect normal boundaries, and where children are possessions not entitled to make their own choices in life.
Trump initially rejected Don Jr. but Don Jr has done everything he can now to earn his father's respect (he'll never has his father's love, because his father is incapable). Depending how you look at it, Don Jr. is trying to create himself in Donald's image, or Donald might well take all the credit for whatever 'success' Don Jr. achieves.
I think the reason Melania keeps Barron as far away from Trump as possible is because she doesn't want Barron to be recreated in his father's image.
But I think we need to humiliate the entire family out of the social realm. They will still be welcome on OANN, but civilized society will reject them.
