Shatner was a douche in the 60s, got over it, yet now spends his time being heckled by people who's general role in Trek was saying "Aye sir!" or fiddling with buttons in the background.
I know which ones have the ego issue and desire for attention. Shatner being so brilliant as Kirk is what helped gain Star Trek's fanbase and what made these people rich. They should be kissing his ass every day.
