Obama did not accept any way but his. He thinks he arrives at his conclusions logically and any other opinion is there fore illogical. He doesn't discuss, he lectures. In short he is a good guy but a piss poor politician. He was elected because he was an outsider (so was Trump) and as an outsider did not know how things worked in DC. A good politician makes a deal where both sides can declare a victory, not try to bend them to his will.
