We live in a time when our nation is thrashing about in fear of the stranger – the foreigner, the refugee, the alien. All our supposed toughness, our “zero tolerance”, our willingness to strip children from their parents’ arms is a result of that fear and insecurity. We fear they make take from us something we have (to which we are certainly entitled!), or keep us from getting something we think we need. People who are afraid build walls, rather than bridges, and take refuge in hatred and prejudice.
