Donald Trump would probably disapprove, since the counter-speech technique could overwhelm his posts of hatred and intolerance
"Speaking at the World Economic Forum in Davos on 20 January, Facebook’s COO Sheryl Sandberg pointed to one source of inspiration for the digital war against Isis – “a ‘like’ attack”.
She explained a recent effort by German Facebook users to “like” the Facebook page of the neo-Nazi party and then post positive messages on the page. “What was a page filled with hatred and intolerance was then tolerance and messages of hope,” she said.
She then pivoted to Isis and added: “The best thing to speak against recruitment by Isis are the voices of people who were recruited by Isis, understand what the true experience is, have escaped and have come back to tell the truth ... Counter-speech to the speech that is perpetuating hate we think by far is the best answer.”"Facebook's Sheryl Sandberg: 'likes' can help stop Isis recruiters | Technology | The Guardian
