Being of a nasty suspicious nature, sometimes. When we get a very emotional/contentious issue posted by someone who never responds and is never heard of again, I do sometimes wonder whether it is some journalist/activist flying a kite hoping we will respond with a series of uncharitable or reactionary views that will make useful ammunition/publicity.
Unfortunately since with very few exceptions most people respond to these posts, thoughtfully and with kindness, anyone looking for a juicy bit of nasty reactionary prose from us is rather disappointed.
