The more anyone insists on calling himself a "journalist," the less likely they are to actually be one.
And anyone who reads news on the air calls himself an "anchor," including some high school kid reading wire copy while working part time at a class D AM.
News readers who call themselves "journalists" are like DJs calling themselves musicians.
The term "anchor" was applied to Walter Cronkite to describe his role in the 1952 political conventions coverage, NOT his role as a news reader.
Anyone who has spent his entire career as "air talent," propped up by writers, editors and producers, has never been a "journalist." But is likely to have developed the kind of tumescent ego that comes to easily to performers. And that's what news readers are. No more, no less.
Not that there's anything wrong with that.
After all, Olivier didn't write Hamlet. But he didn't try to pretend he did either.
