I was born in 1958 and I do remember Cronkite very well. But as far as him having a real effect on me, I really can’t say that.
The article is an example of the typical broad brush “generation” nonsense which tries to link a whole group of people into a category of virtue or vice due to the accident of a similar birth year and bound together by some person or symbol of mass media triviality such as Cronkite. The fact the the cultural symbol here is a deceased leftist newsreader makes this piece even more hilarious than most of the genre.
