That he does business with one of the richest finances in the world dose not have anything to do with his personal feelings. That's how adults operate. They do not let feelings control their business.
If it benefited your family to deal with somebody you did not like you would likely suck up your feelings and act like the adult. Bottom line Business dealings do not negate personal biases.
Well, I think I see a fundamental difference, here. My principles are not for sale. Go kill my friends, I am not going to toady up to you for a buck. The only reason I would enter into any business arrangement with you would be to crush you and all your line, impoverish you, and put you in the poorhouse or on the street in rags, starving and covered with sores, begging for scraps. Dispassionately, of course. That helps keep the blood off the floor.
So selling out his friends' memories for a buck is okay and "adult", but those same friends memories are a basis for national policy?
As I said, the more I learn about the man, the more I am determined to not vote for him.
