I'm having a hard time seeing their point, when all I can think of is counterpoint. Prior to the Information Age, we lived in a world where our media was spoon fed to us, editing everything to make us believe a narrative. Kennedy was King of Camelot, not a womanizer. Hollywood was sparkles and success, not addictions and failures.
This tool the Internet lets us bypass all the BS and see these people for who they are, just people with problems and opinions, no one worth elevating to a point of authority. Lohan isn't a Mouseketeer anymore, she's an addict. Clinton isn't President anymore, he's tripping off to overseas underage sex parties. In the past, we'd never know the facts, just someone else's "Truth". The IRS had all of the missing backup tapes of Lerner's emails all along, perjuring themselves for the last two years. It isn't revisionism when the truth was hidden in the first place.
