I explained that we provide a forum that gives voice to a wide variety of opinions. If it’s not libelous, a personal attack or a dangerous view, I want people to have their say. A diversity of opinions, a chance to think about a topic from another angle, is a great thing, I told them. You want an echo chamber? That’s what your Facebook feed is for. And if you disagree with something, by all means, compose a rebuttal. Several people did that this week, writing eloquent letters on the topic.
