Ahmed, I sincerely believe that Donald Trump is most concerned with the "security" of America/Americans. Just as I answered your other question concerning Muslims & banning & possible mistreatment, please understand something.
Mr. Trump is stating his opinion with regard to the masses of fleeing immigrants from the Middle East. Surely it is understandable & rational for the leader of any country to make certain those entering one country from another, especially in masses and under duress, be properly vetted.
As is typical of the media, these comments were blown out of proportion & spun by those who live to stir trouble at all costs. We have to listen and investigate the facts. We need to KNOW who said what, when and for what reasons.
I'm not a huge fan of Trump, but what is right and fair is our obligation. I don't believe he is "racist" or an Islamaphobe or any of the slurs being thrown around. He does have grave concern for the country & for that we should be grateful.
