His recent tweet is really misleading.
The terrorist said 'God willing', not 'By God's will'. 'God willing' means 'if God allows this', not 'God's telling me to do this'. They think it will please their god, not their god is telling them to do it, hence why it's true that these people aren't a true depiction of Islam. They're a minority that thinks this is what their god wants.
As President-elect, Trump should really be quoting directly from his sources, rather than spreading, you guessed it, fake news.
