People are blind to trust someone who blamed the victims of Muslim terrorism. I may not agree with everything she did, but after two Muslims tried to attack an event in Texas, excusing what they did is terrible.
It was taunting them. However, in a good way the taunting brings things to a head. It brings the violent out into the open faster for law enforcement to deal with them.
Also, Mr. Trump seems to have learned more about Islam this past year. Perhaps he will voice the reality that Islam is a domination ideology seeking to bring into submission all nations and cultures. Per Islam, this attack in Brussels is defensive because Westerners in general and Brussels in particular are offensively attacking Allah and Islam by not submitting to Islam.
