Actually nothing he’s done since getting elected has disturbed me until this meeting. Other than “President-elect Trump” I can’t see a smart reason for this meeting. But I’ll reserve judgment.
His meetings will not bother me. Until I see actions, I wont judge him by who he meets with.
You learn nothing by only meeting with people who agree with you.
Like the Japanese Emperor in WWII. He had surrounded himself with so many yes-men he thought they were winning the war, until he started waking up to find some of his cities were missing.
