"The incendiary racist language and ‘othering’ of British and American Muslims, the fake facts, fake news and demonizing of immigrants has created an environment where open bigotry is flourishing."
That is my comment also & the U.S. will resent the anger of Terrorists fueled by mr. Trump who as individuals will use this as an excuse to attack. The Black people of America struck back as they could. 
mr. trump has now given many moderaate Muslims a reason to "strike back" & their friends a reason also.
