@Hound55 Missing the forest for the trees here, the issue is the racefaking that was (and continues to be) instrumental to the career of one of the most influential people in the comic industry.
See, you're reading an intent in there with racefaking... and I don't think it was there. At least initially.
He's a guy who's long had an interest in Japanese comic and graphic novel culture and I suspect picked a pseudonym which he felt was "cool".
Biggest racial issues came later when he found himself in too deep ad developed a backstory for the pseudonym and (much more relevant) the cultural appropriation because he dealt with typical tropes and concepts from a pretty Westernised view (which to some extent is unsurprising... he's working in comics and existing Marvel concepts which are themselves Westernised concepts picked up from popular culture - closer to a photocopy of a photocopy... - which I personally find more offensive because I hate when they do that shit with Australian/Aboriginal stuff)
He wasn't doing it "to get his foot in the door" or "to get ahead", he already had a job. And the pen name disappeared the second he was able to legally write in his own name, so I'm not sure how it continues to be instrumental either... particularly since it's public knowledge he was using the pseudonym and has been for about five years and is a source of embarrassment for him.
Of all the shitty things in comics, this wouldn't crack my top 20. And if it happened in TV or film media it wouldn't make the top hundred.
I've signed correspondence 'Houndito Brigande' for years, Hell, I think it's still my twitter... it's not because I'm racefaking as Latino, it's because I like Al Pacino movies. Started that about a half decade before Cebulski did, I suspect for similar reasons.
Where it becomes murky is whe you start backstorying a character for said pen name - which he did and apologised for (unsurprising though... he was covering up a breach of contract - not because he was circumventing in-house rules to preserve diversity and affirmative action, but rules designed to preserve creators rights)- as it starts to suggest people are "trying on" a cultural identity as an outfit... which is ignorant of the fact that many people are not in a position of privilege to remove said outfit when it becomes inconvenient for them.
Which is before we get to the significant upscaling of diversity from across the Pacific at Marvel since his employment BECAUSE of that interest he has in Japanese comics and culture... the likes of Gurihiru... and Marvel Voices wouldn't have happened without him, to name a few recent examples off the top of my head.
