Sounds like I'm not the one with a bias here. And who said anything about "everyone" needing a claim to fame? Hel, how is saying Tim showed that Robin could carry a solo even a claim to fame? It's not, and I'm confused why you're acting like folks are proclaiming Tim the greatest work of fiction to ever exist.
Huh. I must have missed his big successful solo run in the very first "Robin" title then. Or was it a "Robin" tv show that I missed?
And who's arguing that the value of Robin started with Tim? Nobody. But when you talk solo title? No Robin had one before Tim. Dick's Golden Age features don't, IMO, count as a solo book. Obviously Robin was a global icon before the people who invented Tim Drake were even born. But while Dick proved that Robin could work great as a sidekick, a team leader/member, with or without Batman, and as a feature in anthologies, he was never given the opportunity to prove himself with a solo Robin title.
I suspect you saw the posts saying "Tim proved Robin could carry a solo" and somehow thought it meant "The only Robin that ever mattered is Tim and everyone else sucks, especially Dick Grayson!"
When did larger media get brought into this? But that's a non-starter. Larger media cherry picks what they want from across all the Robins. Dick in Young Justice has Tim's computer skills and staff. The dead Robin in BvS was Dick, not Jason. The Robin in Teen Titans GO is Dick, but wears Tim's suit, uses his weapon, and otherwise bears no real resemblance to any of the Robins in the comics. One of the cartoons that used Tim gave him, I think, Jason's origin (could be wrong?).
The only exception currently is Damian. He's largely treated as his own individual character and adaptations haven't made too many changes to him. But all the others get mashed together depending on what the story wants.
And us Dick fans can still enjoy Nightwing without tearing down anyone else who ever used the name he built.
Seems like you got an axe to grind with Tim, and I get that. DC ruined that character. But his first stint as Robin, before DC totally wrecked him? Yeah, those were better solo stories than what Dick got as Robin. In my opinion, obviously, I won't hate on the folks who think those Golden Age features were better written or had more depth or character development. Dick is infinitely more important a character and a better character in general, but as far as careers as Robin go? Dick's had some amazing flashback tales, especially lately in stuff like Waid's World's Finest, Yang's Superman-Batman, and Lemire's Robin & Batman. But the original source material? Tim's stuff as Robin is better.
Between the two, Dick is obviously superior. So why is it so hard to say "Yeah, the first Robin solo was Tim, and he carried it for years and proved 'Robin' could carry a title"? That's just the facts.
