What is the speaker's opinion on the temporary ban on immigration from certain Arab countries, and how do they justify it?
"It discriminates against muslims".
The temporary ban is against 6 arab countries who happen to be islamic in nature. It's perfectly clear to any sane person, the beheaders, those who stone the women, gay assassins, body bombs, come from this nations, for those who do not comprehend, these are places of grave concern for the lives of American citizens.
 Russians, Chinese, Indians, South Americans, etc, aren't the ones causing so much distress in the world. What a hypocrisy. 
So yes, you need to identify the enemy, Obama, Trudeau, don't know who the terrorists are, they can't identify them,. Weaklings.
