In our era of social media, reasoned dialogue does not fare especially well. Too many of us are tempted to post short pithy memes containing half truths at best, all in an effort to score points against opponents whom we will almost certainly fail to persuade.
In more than one place I have seen one such meme directed against those who may harbour doubts about the legality of current deportation policies in the United States. It runs as follows: if immigrants failed to respect due process in entering the country illegally, why should they themselves expect to be treated in accordance with due process? On the surface this may sound right to some. But there is an obvious flaw in this reasoning: what if we were to apply it to ordinary criminals, for example, those who commit theft or murder? It would upend the constitutional guarantee of a fair trial for those alleged to have committed such crimes.
