With the dominant tendency in Globe comments being nativist right-wing these days, many of my comments don't make it past the peer-review system, no matter how factual and non-personal they are.  I have many deleted or don't make it every day. 

Typically, several readers have 'disagreed' with mine; but nobody has replied.  In that case it simply disappears without a trace - so of course you don't see it. 

Sometimes I have to agree the comment violated Globe guidelines, but other times, as you say, it's nothing but unpopular fact.

Yet as I said, it's almost always the right-wingers who whine about it.
