How come no one ever suggests wild, mad theories about how nice someone back then was?
Lowbrow entertainment gossip is almost as old as the film business, but now more than ever, filth sells to a culture with an overwhelming thrist for filth, with the media--including so-called legitimate news sources encouraging it. This allows Takei to go on and on like the screaming girl he is, trying to convince the world that Sulu was on the fasttrack for "higher office," while that same world knows he was a bit player at best.
Honestly, Takei's position would be as assbrained if the late Stafford Repp (Batman
's Chief O'Hara) spent the remainder of his life claiming O'Hara was supposed to be as important as the superheroes, but blamed Adam West or Burt Ward for removing lines which would have elevated the character to that never-gonna-happen level.
Thankfully, some supporting actors understood their position, while others....well others turned into Takei.
