Do I really have to clarify that I was being facetious? I thought the "Make Comics Great Again" would have given it away.
Anyway, of course they aren't going to permanently replace Tony Stark, or Peter Parker, or Bruce Banner. But I think it's awesome that they're opening the door for more diverse characters to play in the big kid pool. There have always been minority characters in comics, but the vast majority of them are not even remotely close to being as iconic and well known/loved as their white counterparts. Black Panther, Luke Cage, Black Lightning, John Stewart were barely a thing when I was growing up in the 80's. Fortunately, that's been changing over the last 15+ years, and more minority characters are getting the limelight, and a lot of that is because they are wearing the tights of pre-existing and beloved characters. It may rustle the feathers of a certain type of comic reader, but it's not like Miles Morales is replacing Peter Parker.
It just seems to me that the irritation when a character picks up the mantle of a well known character only arises when the character is a minority.
Dick Grayson has become Batman more than a few times when Bruce has gone MIA for whatever reason, and nobody seems to go apeshit over it. Doc Ock put his mind inside of Peter Parker's body in an absurd (yet highly entertaining) story arc, but people lose their shit when Miles becomes Spider-Man after the death of Peter Parker? If comics have taught us anything, it's that these fuckers always come back. Tony will be Iron Man again. Bruce will be Hulk again. Male Thor will be Thor again. That's how comics work, it's cyclical. I just think that it's cool that the mantles are being handed over to diverse group of characters instead of young white male protege #1,000,652. It's a nice change of pace. I have no problems with young white male protege #1,000,652, obviously, but I do like seeing different people being represented as badasses and heroic, and in major roles/characters. Damien Wayne is a shitstain, but he's also one of my favorite Robins. Then again, has there really ever been a bad Robin besides Jason Todd? I think I've liked them all, with Tim and Damien being my favorites.
Personally, I don't care if a new character takes over a role for an existing hero. Sam Wilson and Bucky as Captain America lead to some cool stories with those characters, and cool Cap stories. In the end, we all know Steve will be back. Peter will be back. Tony will be back. It's why I'll never understand when people get furious when changes like this with Riri happen. As long as the stories are cool and entertaining, I don't care. Kamala Khan is one of my favorite new superheroes, and I love Carol Danvers too (when she's written well). I don't know. I guess I'll never be on the side of the argument that is against adding diversity to a series, including having that diverse character become an existing hero.
