First of all the American people should decide whether Mr. Trump is their actual President. Half of the country thinks he is a misogynist, racist and mad. He proved it many times. No offense, but Mr. Trump has been selected by the decision makers of America and he is not elected by the American people, this what I believe.
Now come to the question of banning immigrants from Muslim countries (Libya, Iraq, Iran, Somalia, Yemen, Sudan, Syria). Ban? Really? Can America's richest one percent and its establishment answer for the destruction, war, terrorism and loss of hundred of thousands of lives. These are the horrible things the policemen (USA) of this world brought to that seven countries. They cannot because the crime they committed is too heavy for them to answer for.
Trump or whoever has no right to ban immigrants from any country. How about if different countries start banning American citizens from entering their soil.
Trump lives in an ideal world and he is ignorant of reality. So it is no shock that he banned immigrants from Muslim countries.
There are a lot of things to say but I will stop here!
