LOL, freeeeeeeeeeeeeeeeee thinks the President of the United States does not know people hate, disagree with, think he is Hitler, Saddam, OBL, mendacious, devious and sinister??
And if they only could get those signs in front of his face, he would change his policies or resign?
Hilarious and sad.
It matters not what he thinks of the protesters, or if their message has any effect on him.
It does matter that he respects the basic rights of the American people of free speech and assembly.
